Number of Registered Studies With Posted Results Over Time

This graph and table show the number of registered studies with results posted on ClinicalTrials.gov, based on the Results First Received Date. ClinicalTrials.gov launched its results database in September 2008, at which time sponsors or investigators were allowed to begin submitting results for their registered studies. The results database was developed to accommodate results submission requirements outlined in FDAAA.
