Fig. 1

Global locations and numbers of first and corresponding authors of Cochrane and non-Cochrane systematic reviews from 50 countries. Note: The light gray color indicates no data (i.e., no authors with affiliations in that country). Maximum number of unique authors is 170 because we did not include authors contributing to both Cochrane and non-Cochrane reviews in the generation of the figure so as to not double count them (e.g., two authors from China contributed to both and thus the maximum is reduced from 172 to 170). See Table 2 for exact numbers and proportions of authors in each country, including the 11 authors who contributed to both Cochrane and non-Cochrane reviews
