Annual and cumulative numbers of projects with publicly available data on the Systematic Review Data Repository (SRDR) website since the year after SRDR’s inception in 2012 (i.e., 2013 to 2019). Note: Data for 2019 only includes January 1, 2019 to November 12, 2019. The spike in the number of projects in 2019, although it includes data from only approximately 10.5 months is because we recently reached out to leads of all existing projects in SRDR to encourage them to make the project data available publicly. Blue bars = annual number of projects. Green bars = cumulative number of projects
