Sex/gender coding and properties of studies at time of data collection on 26 January 2021. Studies are reported according to different analytical criteria. Color blocks represent one category of analysis. Studies are exclusively allocated to one category per analysis, with the exception of the “intervention” category. Here, studies can propose multiple interventions and, hence, appear under each unique intervention type they include. In the facility section, we focus on the number (single or multiple) and location (US or non-US) of the facilities recruiting participants into the studies. Address information for facilities is available for 89% of our full COVID-19 set. All studies (except the 26 Expanded Access) provide enrollment details and they are mostly ‘anticipated’, i.e. target numbers (80%).
