Systematic reviews are necessary to synthesize available evidence and inform clinical practice and health policy decisions. There has been an explosion of evidence available in many fields; this makes it challenging to keep evidence syntheses up to date and useful. Comparative effectiveness systematic reviews are informative; however, producing these often-large reviews bring intense time and resource demands. This commentary describes the implementation of a systematic review using a collaborative model of evidence synthesis. We are implementing the collaborative review model to update a large Cochrane review investigating the efficacy and comparative effectiveness of the design, delivery, and type of exercise treatment for people with chronic low-back pain. Three key benefits of the collaborative review model for evidence synthesis are (1) team coordination and collaboration, (2) quality control measures, and (3) advanced comparative and other analyses. This new collaborative review model is developed and implemented to produce and share high-quality, comparative evidence more efficiently while building capacity and community within a research field.

General Medicine - Abstract
ObjectivesAlthough many trials have assessed the effect of acupuncture on knee osteoarthritis (KOA), its efficacy remains controversial. Sham acupuncture techniques are regarded as representative control interventions in acupuncture trials and sometimes incorporate the use of sham devices (base units) to support a non-penetrating needle. To achieve successful blinding, these trials also use acupuncture base units in the verum acupuncture group. Base units are not used in real-world clinical settings. We aimed to assess the effect sizes of verum and sham acupuncture for KOA in sham-controlled trials with or without base units.MethodsA total of 10 electronic databases for randomized controlled trials (RCTs) comparing the efficacy of verum manual acupuncture and sham acupuncture for the treatment of KOA were searched for articles published before April 12, 2022. The primary outcome was pain intensity, and the secondary outcomes included physical function. The first assessment after the end of treatment was chosen for analysis. Effect sizes are reported as standardized mean differences (SMDs) with 95% confidence intervals (95% CIs). The risk of bias was assessed using the Cochrane risk of bias tool, and publication bias was evaluated using a funnel plot and Egger’s test. The quality of evidence for estimates was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach.ResultsFifteen RCTs were included. There was generally a low risk of bias except for the difficulty in blinding acupuncture therapists (performance bias). Compared to verum acupuncture in sham-controlled trials using base units, verum acupuncture in sham-controlled trials without base units was more effective for improving pain (SMD −0.56, 95% CI −1.09 to −0.03) and function (SMD −0.73, 95% CI −1.36 to −0.10) in KOA. The quality of evidence for network estimates was moderate to low due to the risk of bias and imprecision.ConclusionThese findings suggest that verum acupuncture in different types of sham-controlled trials has different effect sizes for KOA. Because base units are not used in clinical settings, the results of verum acupuncture in sham-controlled trials with base units need to be interpreted carefully.Systematic review registrationhttps://www.researchregistry.com/browse-the-registry#registryofsystematicreviewsmeta-analyses/registryofsystematicreviewsmeta-analysesdetails/6269f962606c5e001fd8790c/, identifier reviewregistry1351.

Radiotherapy and chemotherapy are used to improve survival in colorectal cancer but adverse effects can be a problem. Severe adverse effects may result in dose reduction or cessation of treatment, which have an impact on survival. Coriolus versicolor (Trametes versicolor or 'Turkey Tail') mushroom and its extracts have been used by cancer patients to help with adverse effects.To assess the effects of adjunctive Coriolus versicolor (Trametes versicolor) and its extracts on adverse effects and on survival during colorectal cancer treatment (chemotherapy and radiotherapy) compared with no adjunctive treatment.We searched databases including CENTRAL, MEDLINE, Embase, AMED and CINAHL, Chinese and Japanese databases, and trials registers to 12th April 2022 without restriction of language or publication status. We screened reference lists and attempted to contact researchers in the field to identify additional studies.We included randomised controlled trials (RCTs) investigating the efficacy and safety of Coriolus versicolor and its extracts in adult participants with a confirmed diagnosis of colorectal cancer, in addition to conventional treatment. Interventions included any preparation of Coriolus versicolor (raw, decoction, capsule, tablet, tincture, extract, injection), any part of the fungus (cap, stem, mycelium or whole), in any dose or regimen. Outcomes included adverse events rates, survival, disease progression and recurrence, response rates and quality of life.Two review authors independently screened and selected studies, extracted outcome data, and assessed risk of bias. We evaluated the overall certainty of evidence using the GRADE approach.We included seven parallel RCTs (1569 participants). Six studies (1516 participants) were conducted in Japan and one study (53 participants) in China. Studies included both male and female participants with colorectal cancer (five studies), colon cancer (one study) or rectal cancer (one study). Participants were diagnosed with cancer ranging from stage II to stage IV. Coriolus was used in the form of an extract in all seven studies and was generally used after curative resection, although in one study it was used preoperatively. Duration of treatment with the extract varied between four weeks and three years. Chemotherapeutic regimens in six studies consisted of an oral fluoropyrimidine which was preceded by weekly intravenous 5-Fluorouracil (5-FU) in one study, by mitomycin C in two studies, and which was combined with folinic acid (Leucovorin) in two studies and with radiotherapy preoperatively in one study. XELOX (oxaliplatin intravenous infusion and capecitabine) was used in the remaining study. We found very low-certainty evidence of little to no effect of adjunctive treatment with Coriolus (in the form of an extract, polysaccharide-Krestin, PSK) on withdrawal from treatment due to adverse events (risk ratio (RR) 1.03, 95% confidence interval (CI) 0.45 to 2.34; 703 participants; 3 studies;). We are uncertain whether adjunctive Coriolus versicolor and its extracts compared to usual care alone resulted in a difference in adverse events including neutropenia (RR 0.41, 95% CI 0.24 to 0.71; 133 participants; 3 studies; very low certainty), oral cavity disorders such as oral dryness and mucositis (RR 0.37, 95% CI 0.13 to 1.03; 1022 participants; 5 studies; very low certainty), nausea (RR 0.73, 95% CI 0.44 to 1.22; 969 participants; 4 studies; very low certainty), diarrhoea (RR 0.77, 95% CI 0.32 to 1.86; 1022 participants; 5 studies; very low certainty), and fatigue (RR 0.76; 95% CI 0.33 to 1.78; 133 participants; 3 studies; very low certainty). We found low-certainty evidence of a small effect of adjunctive Coriolus on improved survival at five years compared with no adjunctive care (RR 1.08, 95% CI 1.01 to 1.15; 1094 participants; 3 studies; number needed to benefit (NNTB) = 16 (95% Cl 9 to 70). The effect at earlier time points was unclear.Due to the very low certainty of evidence, we were uncertain about the effect of adjunctive Coriolus (in the form of an extract PSK) on adverse events resulting from conventional chemotherapy for colorectal cancer. This includes effects on withdrawal of treatment due to adverse events and on specific adverse outcomes such as neutropenia and nausea. The uncertainty in the evidence also means that it was unclear whether any adverse events were due to the chemotherapy or to the extract itself. While there was low-certainty evidence of a small effect on overall survival at five years, the influence of reduced adverse effects on this could not be determined. In addition, chemotherapy regimens used in assessing this outcome do not reflect current preferred practice.

Background Determining which therapies fall under the umbrella of complementary, alternative, and/or integrative medicine (CAIM) is difficult for several reasons. An operational definition is dynamic, and changes depending on both historical time period and geographical location, with many countries integrating or considering their traditional system(s) of medicine as conventional care. We have previously reported the first operational definition of CAIM informed by a systematic search. In the present study, we have developed a comprehensive search string informed by an operational definition of CAIM for systematic bibliographic database search strategies. Methods We developed a single search string for the most common bibliographic databases, including those searchable on the OVID platform (e.g., MEDLINE, EMBASE, PsycINFO, AMED), the EBSCO platform (e.g., ERIC, CINAHL), Scopus, and Web of Science, using the finalised operational definition of CAIM’s 604 therapies. We searched the Therapeutic Research Center’s “Natural Medicines” database for all 604 therapies, and each item’s scientific name and/or synonym was included as a keyword or phrase in the search string. Results This developed search string provides a standardised list of CAIM terms (i.e., keywords and phrases) that may be searched on bibliographic databases including those found on the OVID platform (e.g., MEDLINE, EMBASE, PsycINFO, AMED), the EBSCO platform (e.g., ERIC, CINAHL), Scopus, and Web of Science. Conclusion Researchers can select relevant terms for their CAIM study and insert the keywords/phrases into these databases to receive all accessible data. This search technique can simply be copied and pasted into the search bar of each database to identify research by keywords, which is the most inclusive, or by words in the article title, which is more selective. Given its versatility across multiple commonly used academic platforms/databases, it is expected that this search string will be of great value to those conducting research on CAIM topics involving systematic search strategies.

BackgroundElderberry has traditionally been used to prevent and treat respiratory problems. During the COVID-19 pandemic, there has been interest in elderberry supplements to treat or prevent illness, but also concern that elderberry might overstimulate the immune system and increase the risk of ‘cytokine storm’. We aimed to determine benefits and harms of elderberry for the prevention and treatment of viral respiratory infections, and to assess the relationship between elderberry supplements and negative health impacts associated with overproduction of pro-inflammatory cytokines.MethodsWe conducted a systematic review and searched six databases, four research registers, and two preprint sites for studies. Two reviewers independently assessed studies for inclusion, extracted data from studies, assessed risk of bias using Cochrane tools, and evaluated certainty of estimates using GRADE. Outcomes included new illnesses and the severity and duration of illness.ResultsWe screened 1187 records and included five randomized trials on elderberry for the treatment or prevention of viral respiratory illness. We did not find any studies linking elderberry to clinical inflammatory outcomes. However, we found three studies measuring production of cytokines ex vivo after ingestion of elderberry. Elderberry may not reduce the risk of developing the common cold; it may reduce the duration and severity of colds, but the evidence is uncertain. Elderberry may reduce the duration of influenza but the evidence is uncertain. Compared to oseltamivir, an elderberry-containing product may be associated with a lower risk of influenza complications and adverse events. We did not find evidence on elderberry and clinical outcomes related to inflammation. However, we found evidence that elderberry has some effect on inflammatory markers, although this effect may decline with ongoing supplementation. One small study compared elderberry to diclofenac (a nonsteroidal anti-inflammatory drug) and provided some evidence that elderberry is as effective or less effective than diclofenac in cytokine reduction over time.ConclusionsElderberry may be a safe option for treating viral respiratory illness, and there is no evidence that it overstimulates the immune system. However, the evidence on both benefits and harms is uncertain and information from recent and ongoing studies is necessary to make firm conclusions.

Background: There is a growing body of literature on complementary, alternative, and integrative medicine (CAIM), which offers a holistic approach to health and the maintenance of social and cultural values. Bibliometric analyses are an increasingly commonly used method employing quantitative statistical techniques to understand trends in a particular scientific field. The objective of this scoping review is to investigate the quantity and characteristics of evidence in relation to bibliometric analyses of CAIM literature. Methods: The following bibliographic databases will be searched MEDLINE, EMBASE, PsycINFO, AMED, CINAHL, Scopus and Web of Science. Studies published in English, conducting any type of bibliometric analysis involving any CAIM therapies, as detailed by an operational definition of CAIM adopted by Cochrane Complementary Medicine, will be included. Conference abstracts and study protocols will be excluded. The following variables will be extracted from included studies: title, author, year, country, study objective, type of CAIM, health condition targeted, databases searched in the bibliometric analysis, the type of bibliometric variables assessed, how bibliometric information was reported, main findings, conclusions, and limitations. Findings will be summarized narratively, as well as in tabular and graphical format. Conclusions: To the best of our knowledge, this scoping review will be the first to investigate the characteristics of evidence in relation to bibliometric analyses on CAIM literature. The findings of this review may be useful to identify variations in the objectives, methods, and results of bibliometric analyses of CAIM research literature.

BackgroundThere has been increased interest in the role of cannabis for treating medical conditions. The availability of different cannabis-based products can make the side effects of exposure unpredictable. We sought to conduct a scoping review of systematic reviews assessing benefits and harms of cannabis-based medicines for any condition.MethodsA protocol was followed throughout the conduct of this scoping review. A protocol-guided scoping review conduct. Searches of bibliographic databases (e.g., MEDLINE®, Embase, PsycINFO, the Cochrane Library) and gray literature were performed. Two people selected and charted data from systematic reviews. Categorizations emerged during data synthesis. The reporting of results from systematic reviews was performed at a high level appropriate for a scoping review.ResultsAfter screening 1975 citations, 72 systematic reviews were included. The reviews covered many conditions, the most common being pain management. Several reviews focused on management of pain as a symptom of conditions such as multiple sclerosis (MS), injury, and cancer. After pain, the most common symptoms treated were spasticity in MS, movement disturbances, nausea/vomiting, and mental health symptoms. An assessment of review findings lends to the understanding that, although in a small number of reviews results showed a benefit for reducing pain, the analysis approach and reporting in other reviews was sub-optimal, making it difficult to know how consistent findings are when considering pain in general. Adverse effects were reported in most reviews comparing cannabis with placebo (49/59, 83%) and in 20/24 (83%) of the reviews comparing cannabis to active drugs. Minor adverse effects (e.g., drowsiness, dizziness) were common and reported in over half of the reviews. Serious harms were not as common, but were reported in 21/59 (36%) reviews that reported on adverse effects. Overall, safety data was generally reported study-by-study, with few reviews synthesizing data. Only one review was rated as high quality, while the remaining were rated of moderate (n= 36) or low/critically low (n= 35) quality.ConclusionsResults from the included reviews were mixed, with most reporting an inability to draw conclusions due to inconsistent findings and a lack of rigorous evidence. Mild harms were frequently reported, and it is possible the harms of cannabis-based medicines may outweigh benefits.Systematic review registrationThe protocol for this scoping review was posted in the Open Access (https://ruor.uottawa.ca/handle/10393/37247).

Cochrane is an international non-profit organization established in 1993 to produce and disseminate high quality and unbiased systematic reviews of evidence on health care interventions. At the forefront of systematic review methodology, Cochrane is generally accepted to be among the most carefully prepared and rigorous sources of systematic review evidence. There are numerous Cochrane reviews on nonpharmacologic interventions for pain and multiple Cochrane reviews evaluating acupuncture therapy in pain conditions. But how complete and up to date are those reviews relative to other rigorous systematic reviews with meta-analyses of acupuncture therapy for pain published in the literature? In this ‘snapshot’ overview, we found 22 relevant Cochrane reviews, some concluding that acupuncture therapy is probably useful for treating specific pain conditions. However, many of the conditions for which acupuncture is most commonly used are either not represented in Cochrane reviews or the existing Cochrane reviews are seriously outdated and do not reflect current evidence. This creates confusion with the risks of adverse effects and addiction liability associated with pain medications, the prevalence of chronic pain, the ongoing opioid epidemic and the need for evidence-based options for pain as part of comprehensive pain care. Clinicians and patients want clarification on safe and effective options to treat pain. Issues involving reviewed trials’ inadequate use of sham comparators, of acupuncture as a complex intervention with interactive components and a shift in research focus from efficacy trials to real-world pragmatic trials are discussed in relation to updating Cochrane reviews of acupuncture therapy for pain.

Background Identifying what therapies constitute complementary, alternative, and/or integrative medicine (CAIM) is complex for a multitude of reasons. An operational definition is dynamic, and changes based on both historical time period and geographical location whereby many jurisdictions may integrate or consider their traditional system(s) of medicine as conventional care. To date, only one operational definition of “complementary and alternative medicine” has been proposed, by Cochrane researchers in 2011. This definition is not only over a decade old but also did not use systematic methods to compile the therapies. Furthermore, it did not capture the concept “integrative medicine”, which is an increasingly popular aspect of the use of complementary therapies in practice. An updated operational definition reflective of CAIM is warranted given the rapidly increasing body of CAIM research literature published each year. Methods Four peer-reviewed or otherwise quality-assessed information resource types were used to inform the development of the operational definition: peer-reviewed articles resulting from searches across seven academic databases (MEDLINE, EMBASE, AMED, PsycINFO, CINAHL, Scopus and Web of Science); the “aims and scope” webpages of peer-reviewed CAIM journals; CAIM entries found in online encyclopedias, and highly-ranked websites identified through searches of CAIM-related terms on HONcode. Screening of eligible resources, and data extraction of CAIM therapies across them, were each conducted independently and in duplicate. CAIM therapies across eligible sources were deduplicated. Results A total of 101 eligible resources were identified: peer-reviewed articles (n = 19), journal “aims and scope” webpages (n = 22), encyclopedia entries (n = 11), and HONcode-searched websites (n = 49). Six hundred four unique CAIM terms were included in this operational definition. Conclusions This updated operational definition is the first to be informed by systematic methods, and could support the harmonization of CAIM-related research through the provision of a standard of classification, as well as support improved collaboration between different research groups.

BACKGROUND: The role of vitamin D supplementation as a treatment for COVID‐19 has been a subject of considerable discussion. A thorough understanding of the current evidence regarding the effectiveness and safety of vitamin D supplementation for COVID‐19 based on randomised controlled trials is required. OBJECTIVES: To assess whether vitamin D supplementation is effective and safe for the treatment of COVID‐19 in comparison to an active comparator, placebo, or standard of care alone, and to maintain the currency of the evidence, using a living systematic review approach. SEARCH METHODS: We searched the Cochrane COVID‐19 Study Register, Web of Science and the WHO COVID‐19 Global literature on coronavirus disease to identify completed and ongoing studies without language restrictions to 11 March 2021. SELECTION CRITERIA: We followed standard Cochrane methodology. We included randomised controlled trials (RCTs) evaluating vitamin D supplementation for people with COVID‐19, irrespective of disease severity, age, gender or ethnicity. We excluded studies investigating preventive effects, or studies including populations with other coronavirus diseases (severe acute respiratory syndrome (SARS) or Middle East respiratory syndrome (MERS)). DATA COLLECTION AND ANALYSIS: We followed standard Cochrane methodology. To assess bias in included studies, we used the Cochrane risk of bias tool (ROB 2) for RCTs. We rated the certainty of evidence using the GRADE approach for the following prioritised outcome categories: individuals with moderate or severe COVID‐19: all‐cause mortality, clinical status, quality of life, adverse events, serious adverse events, and for individuals with asymptomatic or mild disease: all‐cause mortality, development of severe clinical COVID‐19 symptoms, quality of life, adverse events, serious adverse events. MAIN RESULTS: We identified three RCTs with 356 participants, of whom 183 received vitamin D. In accordance with the World Health Organization (WHO) clinical progression scale, two studies investigated participants with moderate or severe disease, and one study individuals with mild or asymptomatic disease. The control groups consisted of placebo treatment or standard of care alone. Effectiveness of vitamin D supplementation for people with COVID‐19 and moderate to severe disease We included two studies with 313 participants. Due to substantial clinical and methodological diversity of both studies, we were not able to pool data. Vitamin D status was unknown in one study, whereas the other study reported data for vitamin D deficient participants. One study administered multiple doses of oral calcifediol at days 1, 3 and 7, whereas the other study gave a single high dose of oral cholecalciferol at baseline. We assessed one study with low risk of bias for effectiveness outcomes, and the other with some concerns about randomisation and selective reporting. All‐cause mortality at hospital discharge (313 participants) We found two studies reporting data for this outcome. One study reported no deaths when treated with vitamin D out of 50 participants, compared to two deaths out of 26 participants in the control group (Risk ratio (RR) 0.11, 95% confidence interval (CI) 0.01 to 2.13). The other study reported nine deaths out of 119 individuals in the vitamin D group, whereas six participants out of 118 died in the placebo group (RR 1.49, 95% CI 0.55 to 4.04]. We are very uncertain whether vitamin D has an effect on all‐cause mortality at hospital discharge (very low‐certainty evidence). Clinical status assessed by the need for invasive mechanical ventilation (237 participants) We found one study reporting data for this outcome. Nine out of 119 participants needed invasive mechanical ventilation when treated with vitamin D, compared to 17 out of 118 participants in the placebo group (RR 0.52, 95% CI 0.24 to 1.13). Vitamin D supplementation may decrease need for invasive mechanical ventilation, but the evidence is uncertain (low‐certainty evidence). Quality of life We did not find data for quality of life. Safety of vitamin D supplementation for people with COVID‐19 and moderate to severe disease We did not include data from one study, because assessment of serious adverse events was not described and we are concerned that data might have been inconsistently measured. This study reported vomiting in one out of 119 participants immediately after vitamin D intake (RR 2.98, 95% CI 0.12 to 72.30). We are very uncertain whether vitamin D supplementation is associated with higher risk for adverse events (very low‐certainty). Effectiveness and safety of vitamin D supplementation for people with COVID‐19 and asymptomatic or mild disease We found one study including 40 individuals, which did not report our prioritised outcomes, but instead data for viral clearance, inflammatory markers, and vitamin D serum levels. The authors reported no events of hypercalcaemia, but recording and assessment of further adverse events remains unclear. Authors administered oral cholecalciferol in daily doses for at least 14 days, and continued with weekly doses if vitamin D blood levels were > 50 ng/mL. AUTHORS' CONCLUSIONS: There is currently insufficient evidence to determine the benefits and harms of vitamin D supplementation as a treatment of COVID‐19. The evidence for the effectiveness of vitamin D supplementation for the treatment of COVID‐19 is very uncertain. Moreover, we found only limited safety information, and were concerned about consistency in measurement and recording of these outcomes. There was substantial clinical and methodological heterogeneity of included studies, mainly because of different supplementation strategies, formulations, vitamin D status of participants, and reported outcomes. There is an urgent need for well‐designed and adequately powered randomised controlled trials (RCTs) with an appropriate randomisation procedure, comparability of study arms and preferably double‐blinding. We identified 21 ongoing and three completed studies without published results, which indicates that these needs will be addressed and that our findings are subject to change in the future. Due to the living approach of this work, we will update the review periodically.

Background Prediabetes describes a state of hyperglycemia outside of normal limits that does not meet the criteria for diabetes diagnosis, is generally symptomless, and affects an estimated 38% of adults in the United States. Prediabetes typically precedes the diagnosis of type 2 diabetes, which accounts for increased morbidity and mortality. Although the use of dietary and herbal supplements is popular worldwide, and a variety of single herbal medicines have been examined for glycemic management, the potential of increasingly common polyherbal formulations to return glycemic parameters to normal ranges among adults with prediabetes remains largely unexplored. The purpose of this study is to evaluate the efficacy of a commercially available, polyherbal dietary supplement on glycemic and lipid parameters in prediabetic individuals. Methods In this multi-site, double-blinded, randomized controlled clinical trial, 40 participants with prediabetes will be randomized to either a daily oral polyherbal dietary supplement (GlucoSupreme™ Herbal; Designs for Health®, Suffield, CT, USA; containing cinnamon bark (Cinnamomum cassia), banaba leaf (Lagerstroemia speciosa standardized to 1% corosolic acid), kudzu root (Pueraria lobata standardized to 40% isoflavones), fenugreek seed (Trigonella foenum-graceum standardized to 60% saponins), gymnema leaf (Gymnema sylvestre standardized to 25% gymnemic acid), American ginseng root (Panax quinquefolius standardized to 5% ginsenosides), and berberine HCl derived from bark (Berberis aristata)) or placebo for 12 weeks. Short-, medium-, and comparatively long-term markers of glycemic control (blood glucose and fasting insulin, fructosamine, and glycated hemoglobin/A1c, respectively), and other glycemic parameters (GlycoMark, β-cell function, and insulin sensitivity/resistance) will be obtained. Lipid profile (total cholesterol, LDL, HDL, and triglycerides), inflammation (hs-CRP), progression to type 2 diabetes mellitus, as well as safety indices (ALT, AST) will be obtained. An intention-to-treat analysis will be used to assess changes in study outcomes. Discussion Treatment options for adults with prediabetes are currently limited. This study aims to evaluate the safety and efficacy of a commercially available dietary supplement in the popular, but as yet insufficiently studied, category of polyherbal formulas for the management of glycemic parameters and other biomarkers associated with prediabetes.

Systematic reviews on traditional Chinese medicine (TCM) are constantly increasing. However, if these reviews are to be of practical value, the evidence needs to be relevant, valid, and adequately reported. Cochrane Systematic Reviews (CSRs) are considered as high-quality systematic reviews that can inform health care decision making. Our aim was to provide an overview of the scope, findings, quality and impact of CSRs on the benefits and harms associated with TCM interventions for the treatment and prevention of disease to provide new information for clinical practice and future research.The Cochrane Database of Systematic Reviews was searched up to May 2021, and descriptive characteristics were extracted. The correspondence between the questions asked in the CSRs and the available evidence, conclusions and certainty of findings (according to GRADE assessment), methodological quality (AMSTAR 2), and impact (Altmetric Attention Score [AAS], total citations by guideline, and total citations in Web of Science [WoS]) of CSRs were extracted. Tabular and graphical summaries of these descriptive characteristics were constructed.Of 104 CSRs on TCM identified, 70 diseases belonged to 16 disease systems and contained 1642 primary studies with 157,943 participants. Interventions included Chinese herbal medicine (n = 70), acupuncture (n = 28), TCM exercises (n = 4), and moxibustion (n = 2). Among 1642 primary studies, 662 studies included an intervention group treated with at least one TCM therapy and 980 studies included a combination of therapies. Promising outcomes from the 104 CSRs were divided into endpoint outcomes (34 diseases), doctor- or patient-reported outcomes (27 diseases), and surrogate outcomes (37 diseases). Despite the presence of promising outcomes, only 5/104 CSRs drew overall positive conclusions, 42 CSRs concluded the evidence was insufficient, and 54 failed to draw firm conclusions. GRADE assessments were reported in 41.3% of the CSRs, and the ratings were mostly low or very low. Comparing the questions asked and results obtained, there was frequently a lack of information about specific outcomes. Only 16 CSRs obtained results for all outcomes listed in the methods section. According to AMSTAR 2, 51 CSRs (49.0%) were of low quality. The total number of citations in the WoS was 2135 (mean ± SD: 20.8 ± 21.2), and 38.5% of the CSRs had been cited in guidelines 95 times.Although TCM is commonly used, evidence of its effectiveness remains largely inconclusive. Rigorous high-quality trials are needed to support the performance of high-quality reviews and to increase the evidence base. It is critical to emphasize quality over quantity in future TCM research.

BACKGROUND: Viral epidemics or pandemics of acute respiratory infections (ARIs) pose a global threat. Examples are influenza (H1N1) caused by the H1N1pdm09 virus in 2009, severe acute respiratory syndrome (SARS) in 2003, and coronavirus disease 2019 (COVID‐19) caused by SARS‐CoV‐2 in 2019. Antiviral drugs and vaccines may be insufficient to prevent their spread. This is an update of a Cochrane Review published in 2007, 2009, 2010, and 2011. The evidence summarised in this review does not include results from studies from the current COVID‐19 pandemic. OBJECTIVES: To assess the effectiveness of physical interventions to interrupt or reduce the spread of acute respiratory viruses. SEARCH METHODS: We searched CENTRAL, PubMed, Embase, CINAHL on 1 April 2020. We searched ClinicalTrials.gov, and the WHO ICTRP on 16 March 2020. We conducted a backwards and forwards citation analysis on the newly included studies. SELECTION CRITERIA: We included randomised controlled trials (RCTs) and cluster‐RCTs of trials investigating physical interventions (screening at entry ports, isolation, quarantine, physical distancing, personal protection, hand hygiene, face masks, and gargling) to prevent respiratory virus transmission. In previous versions of this review we also included observational studies. However, for this update, there were sufficient RCTs to address our study aims. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. We used GRADE to assess the certainty of the evidence. Three pairs of review authors independently extracted data using a standard template applied in previous versions of this review, but which was revised to reflect our focus on RCTs and cluster‐RCTs for this update. We did not contact trialists for missing data due to the urgency in completing the review. We extracted data on adverse events (harms) associated with the interventions. MAIN RESULTS: We included 44 new RCTs and cluster‐RCTs in this update, bringing the total number of randomised trials to 67. There were no included studies conducted during the COVID‐19 pandemic. Six ongoing studies were identified, of which three evaluating masks are being conducted concurrent with the COVID pandemic, and one is completed. Many studies were conducted during non‐epidemic influenza periods, but several studies were conducted during the global H1N1 influenza pandemic in 2009, and others in epidemic influenza seasons up to 2016. Thus, studies were conducted in the context of lower respiratory viral circulation and transmission compared to COVID‐19. The included studies were conducted in heterogeneous settings, ranging from suburban schools to hospital wards in high‐income countries; crowded inner city settings in low‐income countries; and an immigrant neighbourhood in a high‐income country. Compliance with interventions was low in many studies. The risk of bias for the RCTs and cluster‐RCTs was mostly high or unclear. Medical/surgical masks compared to no masks We included nine trials (of which eight were cluster‐RCTs) comparing medical/surgical masks versus no masks to prevent the spread of viral respiratory illness (two trials with healthcare workers and seven in the community). There is low certainty evidence from nine trials (3507 participants) that wearing a mask may make little or no difference to the outcome of influenza‐like illness (ILI) compared to not wearing a mask (risk ratio (RR) 0.99, 95% confidence interval (CI) 0.82 to 1.18. There is moderate certainty evidence that wearing a mask probably makes little or no difference to the outcome of laboratory‐confirmed influenza compared to not wearing a mask (RR 0.91, 95% CI 0.66 to 1.26; 6 trials; 3005 participants). Harms were rarely measured and poorly reported. Two studies during COVID‐19 plan to recruit a total of 72,000 people. One evaluates medical/surgical masks (N = 6000) (published Annals of Internal Medicine, 18 Nov 2020), and one evaluates cloth masks (N = 66,000). N95/P2 respirators compared to medical/surgical masks We pooled trials comparing N95/P2 respirators with medical/surgical masks (four in healthcare settings and one in a household setting). There is uncertainty over the effects of N95/P2 respirators when compared with medical/surgical masks on the outcomes of clinical respiratory illness (RR 0.70, 95% CI 0.45 to 1.10; very low‐certainty evidence; 3 trials; 7779 participants) and ILI (RR 0.82, 95% CI 0.66 to 1.03; low‐certainty evidence; 5 trials; 8407 participants). The evidence is limited by imprecision and heterogeneity for these subjective outcomes. The use of a N95/P2 respirator compared to a medical/surgical mask probably makes little or no difference for the objective and more precise outcome of laboratory‐confirmed influenza infection (RR 1.10, 95% CI 0.90 to 1.34; moderate‐certainty evidence; 5 trials; 8407 participants). Restricting the pooling to healthcare workers made no difference to the overall findings. Harms were poorly measured and reported, but discomfort wearing medical/surgical masks or N95/P2 respirators was mentioned in several studies. One ongoing study recruiting 576 people compares N95/P2 respirators with medical surgical masks for healthcare workers during COVID‐19. Hand hygiene compared to control Settings included schools, childcare centres, homes, and offices. In a comparison of hand hygiene interventions with control (no intervention), there was a 16% relative reduction in the number of people with ARIs in the hand hygiene group (RR 0.84, 95% CI 0.82 to 0.86; 7 trials; 44,129 participants; moderate‐certainty evidence), suggesting a probable benefit. When considering the more strictly defined outcomes of ILI and laboratory‐confirmed influenza, the estimates of effect for ILI (RR 0.98, 95% CI 0.85 to 1.13; 10 trials; 32,641 participants; low‐certainty evidence) and laboratory‐confirmed influenza (RR 0.91, 95% CI 0.63 to 1.30; 8 trials; 8332 participants; low‐certainty evidence) suggest the intervention made little or no difference. We pooled all 16 trials (61,372 participants) for the composite outcome of ARI or ILI or influenza, with each study only contributing once and the most comprehensive outcome reported. The pooled data showed that hand hygiene may offer a benefit with an 11% relative reduction of respiratory illness (RR 0.89, 95% CI 0.84 to 0.95; low‐certainty evidence), but with high heterogeneity. Few trials measured and reported harms. There are two ongoing studies of handwashing interventions in 395 children outside of COVID‐19. We identified one RCT on quarantine/physical distancing. Company employees in Japan were asked to stay at home if household members had ILI symptoms. Overall fewer people in the intervention group contracted influenza compared with workers in the control group (2.75% versus 3.18%; hazard ratio 0.80, 95% CI 0.66 to 0.97). However, those who stayed at home with their infected family members were 2.17 times more likely to be infected. We found no RCTs on eye protection, gowns and gloves, or screening at entry ports. AUTHORS' CONCLUSIONS: The high risk of bias in the trials, variation in outcome measurement, and relatively low compliance with the interventions during the studies hamper drawing firm conclusions and generalising the findings to the current COVID‐19 pandemic. There is uncertainty about the effects of face masks. The low‐moderate certainty of the evidence means our confidence in the effect estimate is limited, and that the true effect may be different from the observed estimate of the effect. The pooled results of randomised trials did not show a clear reduction in respiratory viral infection with the use of medical/surgical masks during seasonal influenza. There were no clear differences between the use of medical/surgical masks compared with N95/P2 respirators in healthcare workers when used in routine care to reduce respiratory viral infection. Hand hygiene is likely to modestly reduce the burden of respiratory illness. Harms associated with physical interventions were under‐investigated. There is a need for large, well‐designed RCTs addressing the effectiveness of many of these interventions in multiple settings and populations, especially in those most at risk of ARIs.

IntroductionAntioxidant dietary supplements are used by many patients with cancer to reduce the side effects of chemotherapy and improve prognosis. While some research indicates oral antioxidant supplementation reduces side effects and improves patient survival, other studies suggest the use of antioxidant dietary supplements may interfere with chemotherapy and reduce its curative effects. There is a need to clarify the evidence base on the impact of dietary antioxidant supplementation during chemotherapy on both side effect and treatment efficacy outcomes. We will use a scoping review approach to identify what systematic review evidence exists regarding beneficial and harmful effects of dietary antioxidant supplements when used during cancer treatment.Methods and analysisWe will use Arksey & O’Malley and Joanna Briggs Institute methods for scoping reviews. We will systematically search PubMed, Embase, CINAHL, Scopus, Dissertations & Theses Global and the Cochrane Library from inception to October 2020. Systematic reviews of randomised controlled trials of oral dietary antioxidant supplements used by participants receiving curative chemotherapy, radiotherapy or other biological therapy for cancer will be eligible. Two reviewers will screen citations and full texts for inclusion and chart data on research questions from included reviews. Two reviewers will assess the overall confidence in systematic review results using A Measurement Tool to Assess Systematic Reviews-2 (AMSTAR-2), and summarised evidence will focus on reviews rated at high or moderate overall confidence. Tables will be used to map existing evidence and identify evidence gaps for safety and effectiveness outcomes.Ethics and disseminationThis scoping review does not require ethical approval as it is a secondary assessment of available literature. The results will be presented at conferences and submitted for publication in a peer-reviewed journal. We will also disseminate results to community and clinical stakeholders and involve them in developing subsequent research to address critical existing gaps in the evidence as identified by the scoping review.

Background and Objective Randomized trials may be designed to provide evidence more strongly related to efficacy or effectiveness of an intervention. When systematic reviews are used to inform clinical or policy decisions, it is important to know the efficacy–effectiveness nature of the included trials. The objective of this study was to develop a tool to characterize randomized trials included in a systematic review on an efficacy–effectiveness continuum. Methods We extracted rating domains and descriptors from existing tools and used a modified Delphi procedure to condense the domains and develop a new tool. The feasibility and interrater reliability of the tool was tested on trials from four systematic reviews. Results The Rating of Included Trials on the Efficacy–Effectiveness Spectrum (RITES) tool rates clinical trials on a five-point Likert scale in four domains: (1) participant characteristics, (2) trial setting, (3) flexibility of interventions, and (4) clinical relevance of interventions. When RITES was piloted on trials from three reviews by unaffiliated raters, ratings were variable (intraclass correlation coefficient [ICC] 0.25–0.66 for the four domains); but, when RITES was used on one review by the review authors with expertise on the topic, the ratings were consistent (ICCs > 0.80. Conclusion RITES may help to characterize the efficacy–effectiveness nature of trials included in systematic reviews.

IntroductionTraditional East Asian medicine (TEAM) is widely used in Asia and increasingly in the West. Systematic reviews (SRs) are the best summaries of the potential benefits or harms of interventions, and Cochrane is a leading international SR organization. Cochrane perspectives on the barriers to the initiation and completion of Cochrane SRs of TEAM therapies were solicited.MethodsCochrane Review Groups (CRGs) were identified from the online listing of CRGs at cochrane.org and a link to an online survey was e-mailed to the primary contact for each CRG.ResultsForty-eight responses were received on behalf of 49/53 (92%) CRGs. Most CRGs had experience producing TEAM reviews, primarily in acupuncture or herbal medicine. The main barriers to taking on a new TEAM review were difficulty in understanding and assessing the intervention, and the low priority of TEAM topics. Problems with the quality and accessibility of randomized trials in TEAM were cited as a major concern. CRGs suggested that the quality and accessibility of randomized trials should be improved, that the methodological and language expertise of authors should be enhanced, and that further peer review expertise should be made available to CRGs.ConclusionsTEAM topics are covered in Cochrane reviews but are often considered low-priority. This survey highlights Cochrane concerns about the quality of the underlying evidence base and the training of the author teams as barriers to successful SR completion. Specific approaches are proposed to increase the number of TEAM reviews and address the limitations of TEAM research processes within Cochrane.

BACKGROUND: Hip osteoarthritis (OA) is a major cause of pain and functional limitation. Few hip OA treatments have been evaluated for safety and effectiveness. Acupuncture is a traditional Chinese medical therapy which aims to treat disease by inserting very thin needles at specific points on the body. OBJECTIVES: To assess the benefits and harms of acupuncture in patients with hip OA. SEARCH METHODS: We searched Cochrane CENTRAL, MEDLINE, and Embase all through March 2018. SELECTION CRITERIA: We included randomized controlled trials (RCTs) that compared acupuncture with sham acupuncture, another active treatment, or no specific treatment; and RCTs that evaluated acupuncture as an addition to another treatment. Major outcomes were pain and function at the short term (i.e. < 3 months after randomization) and adverse events. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. MAIN RESULTS: Six RCTs with 413 participants were included. Four RCTs included only people with OA of the hip, and two included a mix of people with OA of the hip and knee. All RCTs included primarily older participants, with a mean age range from 61 to 67 years, and a mean duration of hip OA pain from two to eight years. Approximately two‐thirds of participants were women. Two RCTs compared acupuncture versus sham acupuncture; the other four RCTs were not blinded. All results were evaluated at short term (i.e. four to nine weeks after randomization). In the two RCTs that compared acupuncture to sham acupuncture, the sham acupuncture control interventions were judged believable, but each sham acupuncture intervention was also judged to have a risk of weak acupuncture‐specific effects, due to placement of non‐penetrating needles at the correct acupuncture points in one RCT, and the use of penetrating needles not inserted at the correct points in the other RCT. For these two sham‐controlled RCTs, the risk of bias was low for all outcomes. The combined analysis of two sham‐controlled RCTs gave moderate quality evidence of little or no effect in reduction in pain for acupuncture relative to sham acupuncture. Due to the small sample sizes in the studies, the confidence interval includes both the possibility of moderate benefit and the possibility of no effect of acupuncture (120 participants; Standardized Mean Difference (SMD) ‐0.13, (95% Confidence Interval (CI) ‐0.49 to 0.22); 2.1 points greater improvement with acupuncture compared to sham acupuncture on 100 point scale (i.e., absolute percent change ‐2.1% (95% CI ‐7.9% to 3.6%)); relative percent change ‐4.1% (95% CI ‐15.6% to 7.0%)). Estimates of effect were similar for function (120 participants; SMD ‐0.15, (95% CI ‐0.51 to 0.21)). No pooled estimate, representative of the two sham‐controlled RCTs, could be calculated or reported for the quality of life outcome. The four other RCTs were unblinded comparative effectiveness RCTs, which compared (additional) acupuncture to four different active control treatments. There was low quality evidence that addition of acupuncture to the routine primary care that RCT participants were receiving from their physicians was associated with statistically significant and clinically relevant benefits, compared to the routine primary physician care alone, in pain (1 RCT; 137 participants; mean percent difference ‐22.9% (95% CI ‐29.2% to ‐16.6%); relative percent difference ‐46.5% (95% CI ‐59.3% to ‐33.7%)) and function (mean percent difference ‐19.0% (95% CI ‐24.41 to ‐13.59); relative percent difference ‐38.6% (95% CI ‐49.6% to ‐27.6%)). There was no statistically significant difference for mental quality of life and acupuncture showed a small, significant benefit for physical quality of life. The effects of acupuncture compared with either advice plus exercise or NSAIDs are uncertain. We are also uncertain whether acupuncture plus patient education improves pain, function, and quality of life, when compared to patient education alone. In general, the overall quality of the evidence for the four comparative effectiveness RCTs was low to very low, mainly due to the potential for biased reporting of patient‐assessed outcomes due to lack of blinding and sparse data. Information on safety was reported in four RCTs. Two RCTs reported minor side effects of acupuncture, which were primarily minor bruising, bleeding, or pain at needle insertion sites. Four RCTs reported on adverse events, and none reported any serious adverse events attributed to acupuncture. AUTHORS' CONCLUSIONS: Acupuncture probably has little or no effect in reducing pain or improving function relative to sham acupuncture in people with hip osteoarthritis. Due to the small sample size in the studies, the confidence intervals include both the possibility of moderate benefits and the possibility of no effect of acupuncture. One unblinded trial found that acupuncture as an addition to routine primary physician care was associated with benefits on pain and function. However, these reported benefits are likely due at least partially to RCT participants' greater expectations of benefit from acupuncture. Possible side effects associated with acupuncture treatment were minor.

Background Urinary incontinence in women is associated with poor quality of life and difficulties in social, psychological and sexual functioning. The condition may affect up to 15% of middle-aged or older women in the general population. Conservative treatments such as lifestyle interventions, bladder training and pelvic floor muscle training (used either alone or in combination with other interventions) are the initial approaches to the management of urinary incontinence. Many women are interested in additional treatments such as yoga, a system of philosophy, lifestyle and physical practice that originated in ancient India. Objectives To assess the effects of yoga for treating urinary incontinence in women. Search methods We searched the Cochrane Incontinence and Cochrane Complementary Medicine Specialised Registers. We searched the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) and ClinicalTrials.gov to identify any ongoing or unpublished studies. We handsearched Proceedings of the International Congress on Complementary Medicine Research and the European Congress for Integrative Medicine. We searched the NHS Economic Evaluation Database for economic studies, and supplemented this search with searches for economics studies in MEDLINE and Embase from 2015 onwards. Database searches are up-to-date as of 21 June 2018. Selection criteria Randomised controlled trials in women diagnosed with urinary incontinence in which one group was allocated to treatment with yoga. Data collection and analysis Two review authors independently screened titles and abstracts of all retrieved articles, selected studies for inclusion, extracted data, assessed risk of bias and evaluated the certainty of the evidence for each reported outcome. Any disagreements were resolved by consensus. We planned to combine clinically comparable studies in Review Manager 5 using random-effects meta-analysis and to carry out sensitivity and subgroup analyses. We planned to create a table listing economic studies on yoga for incontinence but not carry out any analyses on these studies. Main results We included two studies (involving a total of 49 women). Each study compared yoga to a different comparator, therefore we were unable to combine the data in a meta-analysis. A third study that has been completed but not yet fully reported is awaiting assessment.One included study was a six-week study comparing yoga to a waiting list in 19 women with either urgency urinary incontinence or stress urinary incontinence. We judged the certainty of the evidence for all reported outcomes as very low due to performance bias, detection bias, and imprecision. The number of women reporting cure was not reported. We are uncertain whether yoga results in satisfaction with cure or improvement of incontinence (risk ratio (RR) 6.33, 95% confidence interval (CI) 1.44 to 27.88; an increase of 592 from 111 per 1000, 95% CI 160 to 1000). We are uncertain whether there is a difference between yoga and waiting list in condition-specific quality of life as measured on the Incontinence Impact Questionnaire Short Form (mean difference (MD) 1.74, 95% CI -33.02 to 36.50); the number of micturitions (MD -0.77, 95% CI -2.13 to 0.59); the number of incontinence episodes (MD -1.57, 95% CI -2.83 to -0.31); or the bothersomeness of incontinence as measured on the Urogenital Distress Inventory 6 (MD -0.90, 95% CI -1.46 to -0.34). There was no evidence of a difference in the number of women who experienced at least one adverse event (risk difference 0%, 95% CI -38% to 38%; no difference from 222 per 1000, 95% CI 380 fewer to 380 more).The second included study was an eight-week study in 30 women with urgency urinary incontinence that compared mindfulness-based stress reduction (MBSR) to an active control intervention of yoga classes. The study was unblinded, and there was high attrition from both study arms for all outcome assessments. We judged the certainty of the evidence for all reported outcomes as very low due to performance bias, attrition bias, imprecision and indirectness. The number of women reporting cure was not reported. We are uncertain whether women in the yoga group were less likely to report improvement in incontinence at eight weeks compared to women in the MBSR group (RR 0.09, 95% CI 0.01 to 1.43; a decrease of 419 from 461 per 1000, 95% CI 5 to 660). We are uncertain about the effect of MBSR compared to yoga on reports of cure or improvement in incontinence, improvement in condition-specific quality of life measured on the Overactive Bladder Health-Related Quality of Life Scale, reduction in incontinence episodes or reduction in bothersomeness of incontinence as measured on the Overactive Bladder Symptom and Quality of Life-Short Form at eight weeks. The study did not report on adverse effects. Authors' conclusions We identified few trials on yoga for incontinence, and the existing trials were small and at high risk of bias. In addition, we did not find any studies of economic outcomes related to yoga for urinary incontinence. Due to the lack of evidence to answer the review question, we are uncertain whether yoga is useful for women with urinary incontinence. Additional, well-conducted trials with larger sample sizes are needed.

Background Non-specific low back pain is a common, potentially disabling condition usually treated with self-care and non-prescription medication. For chronic low back pain, current guidelines state that exercise therapy may be beneficial. Yoga is a mind-body exercise sometimes used for non-specific low back pain. Objectives To assess the effects of yoga for treating chronic non-specific low back pain, compared to no specific treatment, a minimal intervention (e.g. education), or another active treatment, with a focus on pain, function, and adverse events. Search methods We searched CENTRAL, MEDLINE, Embase, five other databases and four trials registers to 11 March 2016 without restriction of language or publication status. We screened reference lists and contacted experts in the field to identify additional studies. Selection criteria We included randomized controlled trials of yoga treatment in people with chronic non-specific low back pain. We included studies comparing yoga to any other intervention or to no intervention. We also included studies comparing yoga as an adjunct to other therapies, versus those other therapies alone. Data collection and analysis Two authors independently screened and selected studies, extracted outcome data, and assessed risk of bias. We contacted study authors to obtain missing or unclear information. We evaluated the overall certainty of evidence using the GRADE approach. Main results We included 12 trials (1080 participants) carried out in the USA (seven trials), India (three trials), and the UK (two trials). Studies were unfunded (one trial), funded by a yoga institution (one trial), funded by non-profit or government sources (seven trials), or did not report on funding (three trials). Most trials used Iyengar, Hatha, or Viniyoga forms of yoga. The trials compared yoga to no intervention or a non-exercise intervention such as education (seven trials), an exercise intervention (three trials), or both exercise and non-exercise interventions (two trials). All trials were at high risk of performance and detection bias because participants and providers were not blinded to treatment assignment, and outcomes were self-assessed. Therefore, we downgraded all outcomes to 'moderate' certainty evidence because of risk of bias, and when there was additional serious risk of bias, unexplained heterogeneity between studies, or the analyses were imprecise, we downgraded the certainty of the evidence further. For yoga compared to non-exercise controls (9 trials; 810 participants), there was low-certainty evidence that yoga produced small to moderate improvements in back-related function at three to four months (standardized mean difference (SMD) -0.40, 95% confidence interval (CI) -0.66 to -0.14; corresponding to a change in the Roland-Morris Disability Questionnaire of mean difference (MD) -2.18, 95% -3.60 to -0.76), moderate-certainty evidence for small to moderate improvements at six months (SMD -0.44, 95% CI -0.66 to -0.22; corresponding to a change in the Roland-Morris Disability Questionnaire of MD -2.15, 95% -3.23 to -1.08), and low-certainty evidence for small improvements at 12 months (SMD -0.26, 95% CI -0.46 to -0.05; corresponding to a change in the Roland-Morris Disability Questionnaire of MD -1.36, 95% -2.41 to -0.26). On a 0-100 scale there was very low- to moderate-certainty evidence that yoga was slightly better for pain at three to four months (MD -4.55, 95% CI -7.04 to -2.06), six months (MD -7.81, 95% CI -13.37 to -2.25), and 12 months (MD -5.40, 95% CI -14.50 to -3.70), however we pre-defined clinically significant changes in pain as 15 points or greater and this threshold was not met. Based on information from six trials, there was moderate-certainty evidence that the risk of adverse events, primarily increased back pain, was higher in yoga than in non-exercise controls (risk difference (RD) 5%, 95% CI 2% to 8%). For yoga compared to non-yoga exercise controls (4 trials; 394 participants), there was very-low-certainty evidence for little or no difference in back-related function at three months (SMD -0.22, 95% CI -0.65 to 0.20; corresponding to a change in the Roland-Morris Disability Questionnaire of MD -0.99, 95% -2.87 to 0.90) and six months (SMD -0.20, 95% CI -0.59 to 0.19; corresponding to a change in the Roland-Morris Disability Questionnaire of MD -0.90, 95% -2.61 to 0.81), and no information on back-related function after six months. There was very low-certainty evidence for lower pain on a 0-100 scale at seven months (MD -20.40, 95% CI -25.48 to -15.32), and no information on pain at three months or after seven months. Based on information from three trials, there was low-certainty evidence for no difference in the risk of adverse events between yoga and non-yoga exercise controls (RD 1%, 95% CI -4% to 6%). For yoga added to exercise compared to exercise alone (1 trial; 24 participants), there was very-low-certainty evidence for little or no difference at 10 weeks in back-related function (SMD -0.60, 95% CI -1.42 to 0.22; corresponding to a change in the Oswestry Disability Index of MD -17.05, 95% -22.96 to 11.14) or pain on a 0-100 scale (MD -3.20, 95% CI -13.76 to 7.36). There was no information on outcomes at other time points. There was no information on adverse events. Studies provided limited evidence on risk of clinical improvement, measures of quality of life, and depression. There was no evidence on work-related disability. Authors' conclusions There is low- to moderate-certainty evidence that yoga compared to non-exercise controls results in small to moderate improvements in back-related function at three and six months. Yoga may also be slightly more effective for pain at three and six months, however the effect size did not meet predefined levels of minimum clinical importance. It is uncertain whether there is any difference between yoga and other exercise for back-related function or pain, or whether yoga added to exercise is more effective than exercise alone. Yoga is associated with more adverse events than non-exercise controls, but may have the same risk of adverse events as other back-focused exercise. Yoga is not associated with serious adverse events. There is a need for additional high-quality research to improve confidence in estimates of effect, to evaluate long-term outcomes, and to provide additional information on comparisons between yoga and other exercise for chronic non-specific low back pain.

Background Delirium is an acute change in mental status characterized by sudden onset, fluctuating course, inattention, disorganized thinking, and abnormal level of consciousness. The objective of the randomized controlled trial “A STrategy to Reduce the Incidence of Postoperative Delirium in Elderly Patients” (STRIDE) is to assess the effectiveness of light versus heavy sedation on delirium and other outcomes in elderly patients undergoing hip fracture repair surgery. Our goal is to describe the design considerations and lessons learned in planning and implementing the STRIDE trial. Methods Discussed are challenges encountered including (1) how to ensure that we quickly identify, assess the eligibility of, and randomize traumatic hip fracture patients; (2) how to implement interventions that involve continuous monitoring and adjustment during the surgery; and (3) how to measure and ascertain the primary outcome, delirium. Results To address the first challenge, we monitored the operating room schedule more actively than anticipated. We constructed and organized eligibility assessment data collection forms by purpose and by source of information needed to complete them. We decided that randomization needs to take place in the operating room. To address the second challenge, we designed and implemented a treatment protocol and covered the bispectral index monitor to prevent the Anesthesiologist/Anesthetist from being influenced by the bispectral index reading while administering the intervention. Finally, clinical assessment of delirium consisted of standardized interviews of the patient using validated instruments, interviews of those caring for the patient, and review of the medical record. A consensus panel made the final determination of a delirium diagnosis. We note that STRIDE is a single-center trial. The decisions we took may have different implications for multi-center trials. Conclusions Lessons learned are likely to provide useful information to others designing trials in emergency and surgical setting and for those who are interested in unbiased assessment of delirium.

Objective Acupuncture systematic reviewers have increasingly searched Chinese databases and journals to identify eligible randomised clinical trials (RCTs). However, reviewers have infrequently searched for eligible RCTs in Korean databases and journals. This study aimed to identify difficult to locate acupuncture RCTs in Korean databases and journals and to assess the characteristics and quality of the identified RCTs. Methods Eleven electronic databases and seven journals were searched up to December 2012. All RCTs using needle acupuncture were considered for inclusion. Key study characteristics were extracted and risk of bias was assessed using the Cochrane Collaboration tool. Results One hundred and forty-three publications met our inclusion criteria. Acupuncture RCTs in the Korean literature emerged in the mid-1990s and increased in the mid-2000s. Diverse methods of acupuncture were used, including some methods unique to Korea (eg, Saam acupuncture). The largest proportion of trials evaluated acupuncture for musculoskeletal conditions (27.3%). The mean sample size was 44.3±25.3 per trial. Random sequence generation methods were reported in 44.8% of the RCTs, whereas only 11.9% reported methods of allocation concealment. A low proportion of trials reported participant blinding (32.9%) and outcome assessment blinding (18.9%). Conclusions Korean acupuncture trials, many of which evaluate acupuncture styles unique to Korea, are typically omitted from systematic reviews of acupuncture, resulting in the potential for language bias. The development of this database of difficult to locate Korean trials, which includes English language translations of abstracts, will enable these trials of varying quality to be assessed for inclusion in future acupuncture systematic reviews.

Review authors in the Cochrane Collaboration conducted a review of the effects of providing long chain polyunsaturated fatty acids (LCPUFA) supplements to breastfeeding mothers for improving child growth and development. After searching for all relevant studies, they found 8 studies which provided LCPUFA to women during pregnancy and breastfeeding or solely during breastfeeding. This summary presents the review findings of the effects of LCPUFA supplementation versus placebo on child growth and neurodevelopmental outcomes after 24 months. LCPUFA and Child Growth and Development Long chain polyunsaturated fatty acids (LCPUFA) such as arachidonic acid (AA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) are important nutrients for the development of the infant nervous system, including the brain and retina. LCPUFA are known as ‘essential’ fatty acids because they are not efficiently produced by the body and are more easily obtained from the diet. LCPUFA may be provided to infants who breastfeed by supplementing the diet of the lactating mother. There has been some research into whether giving LCPUFA supplements to breastfeeding mothers improves the growth, neurodevelopment, and visual ability of children during infancy and early childhood. This review was carried out to summarize the evidence.

Alterations in the composition of the gut microbiota are associated with a number of gastrointestinal (GI) conditions, including diarrhea, inflammatory bowel diseases (IBD) and liver diseases. Probiotics, live microorganisms that may confer a health benefit to the host when consumed, are commonly used as a therapy for treating these GI conditions by means of modifying the composition or activity of the microbiota. The purpose of this overview is to summarize the evidence on probiotics and GI conditions available from Cochrane, a non-profit organization that produces rigorous and high-quality systematic reviews of health interventions. Findings from this overview will help provide more precise guidance for clinical use of probiotics and to identify gaps in probiotic research related to GI conditions.
