To identify true gaps and ensure that reporting guidelines remain a useful tool that is straightforward to use, we are conducting a full audit of the current reporting guidelines’ landscape. We are extracting data on general reporting guidelines characteristics (e.g., scope of guideline, journal and year of publication, length of reporting guideline), methods used to develop the reporting guidelines (e.g., details on any literature review, Delphi survey, consensus process, composition of guideline group, pilot testing), and how they were disseminated (e.g., multiple publications, explanatory document, website). We are using the data collected on development methods to update our taxonomy of reporting guidelines, currently based on their scope (specific to study design, section of the report, clinical area, or a combination of these), and whether the document describes an extension of a previous guideline.
