ClinicalTrials.gov is a freely accessible federal registry of clinical studies on human volunteers maintained by the National Library of Medicine at the National Institutes of Health.
Each record presents summary information about the disease or condition, the tested intervention, approved study protocol, participation requirements and study contact information. Additionally, many records include study results such as participant demographics, outcomes of the study and summaries of any adverse events experienced by study participants. Recent or ongoing studies may provide overview of study measures while completed studies may link to related publications for background or study results.
