- Abstract
Additional file 1: Additional Material 1. Figure showing number of studies published per year. Additional Material 2. Figure indicates the number of studies from each country, measured as the country affiliation of 1st authors. Additional Material 3. Metrics used in studies evaluating redundancy. N = Number of studies. The total number is higher than the actual number of studies evaluating redundancy, because most studies have used more than one metric. Additional Material 4. Table presenting the metrics used in studies evaluating the use of the EBR approach to minimise or avoid redundancy. N = Number of studies. The total number is higher than the actual number of studies evaluating the use of the EBR approach because most studies have used more than one metric. Additional Material 5. Bibliographic map, the M. Clarke group. Additional Material 6. Bibliographic map, the T.C. Chalmers group. Additional Material 7. Table listing the data materials used in the included studies. (Note that “Primary studies” include papers using various kinds of studies as data material, including some systematic reviews.) Fields marked in light green indicate several studies (6 or more), those in light red indicate few studies (5 or less), and those marked in red indicate no studies. The sum of studies evaluating redundancy/use of EBR approach is higher than the total number, because several studies have evaluated more than one research question. Also, one included paper evaluating the use of the EBR approach [8] used both primary studies and researchers as data material and was therefore counted twice in the table. Additional Material 8. Table listing study designs used in the included studies. Fields marked in light green indicate several studies (6 or more), those in light red indicate few studies (5 or less), and those marked in red indicate no studies. The sum of studies evaluating redundancy/use of EBR is higher than the total number, because several studies have evaluated more than one research question. Also, one included paper evaluating the use of the EBR approach [8] used both cross-sectional and another observational study designs and was therefore counted twice in the table. Additional Material 9. Table listing analysis methods used in the included studies. Fields marked in light green indicate several studies (6 or more), those in light red indicate few studies (5 or less), and those marked in red indicate no studies. Note that many of the included studies used more than one analysis method and investigated more than one research question. For that reason, studies are counted several times in the table, and their sum is much higher than the total number of included papers. Additional Material 10. Table presenting an overview of the different conclusions reported in the included studies. N = number of studies. Additional Material 11. Reference list of included studies.
