Additional file 10: of Some data quality issues at ClinicalTrials.gov

Records that list both the name and the role of the investigator. The names of the investigators and their corresponding roles were extracted from Additional file 8: Table S6 (31,833 records) and Additional file 9: Table S7 (3288 records). They were sorted into a “NameAndRole” sheet for trials that listed both the name and role of the investigator, and a “Nulls” sheet that listed the remaining records. The data are presented in the following six Recruitment Type categories: (1) Active, not recruiting (4052 selected records with 383 leftovers), (2) Completed (19,404; 2726), (3) Enrolling by invitation (162; 23), (4) Recruiting (3784; 156), (5) Suspended (182; 11), and (6) Terminated (3808; 430). The sheets for these categories are numbered 1–6, respectively. (XLS 6779 kb)
