Additional file 12: of Some data quality issues at ClinicalTrials.gov

Data in the form of individual investigators and their matching roles. The data (31,375 records from Additional file 11: Table S9) were sorted into a “LineByLine” sheet, where records that contained multiple names and roles were segregated such that each row contains one name and the corresponding role. The data are presented in the following six Recruitment Type categories: (1) Active, not recruiting (4805 records), (2) Completed (24,135), (3) Enrolling by invitation (201), (4) Recruiting (37,248), (5) Suspended (214), and (6) Terminated (4756). The sheets for these categories are numbered 1–6, respectively. (XLS 5686 kb)
