Trial completion reliability score

F 39/100

1,335 of 1,673 decided trials (Completed vs. Terminated on ClinicalTrials.gov) reached their planned completion (79.8%), vs. national p10 68.4% / p90 100% among 1,234 sponsors with at least 10 decided trials. Still-open trials (Recruiting, Active-not-recruiting, Not-yet-recruiting) are excluded since they have not reached an outcome yet.
