FAQ: Clinical Trial Results
Question: How can I find the results of a clinical trial?
Answer: If the results are published, you may find them if you search the following:
- NLM MEDLINE/PubMed (search for the name of the study, study number, or use the subset - clinicaltrials.gov[si] in your strategy)
http://pubmed.gov
You can also use these strategies:
- Search for clinical trials as a publication type: (disease AND clinicaltrials [pt])
- Search for the name of the study's principal investigator or collaborators: (disease AND last name [ir])
- University of Maryland HS/HSL Clinical Trials Links

Please note:
- Trial results may not be available even after a clinical trial ends.
- Sometimes, trials end before completion, and researchers never publish the results
- In some cases, NIH issues a clinical alert in advance of a completed trial or publication. The alert may be the only information published. NIH Clinical Alerts are at
