Additional file 11 of Some data quality issues at ClinicalTrials.gov

Records that list matching numbers of names and roles of the investigators. The data (31,392 records from Additional file 10: Table S8) were sorted into the “MatchedPipes” sheet, where the number of pipes (each one of which delineates one name or role) was the same in the name and corresponding role cells, and an “UnmatchedPipes” sheet with the remaining records. The data are presented in the following six Recruitment Type categories: (1) Active, not recruiting (4051 selected records with 1 leftover), (2) Completed (19,392; 12), (3) Enrolling by invitation (162; 0), (4) Recruiting (3782; 2), (5) Suspended (181; 1), and (6) Terminated (3807; 1). The sheets for these categories are numbered 1–6, respectively. (XLS 6429 kb)
