The study results will be displayed in a tabular format that includes the following information:

If no results have been posted on, the results tab is labeled "No Study Results Posted." See About the Results Database for more information.

Find Studies With Results Posted on

To search for studies with results posted on, go to Advanced Search and select "Studies With Results" from the Study Results field dropdown list. You can also enter additional search terms in the other fields. See How to Use Advanced Search for more information.

Do not select "Open Studies" from the Recruitment field if you want to find studies with results posted on Results are only posted for closed studies, meaning studies that are no longer recruiting.

Find Studies With Results Published in a Medical Journal

Study results are often published in medical journals. On, publication citations are displayed at the bottom of the Full Text View tab of a study record, under the More Information heading.

Publications are identified in two ways:

  • Citations submitted by sponsors or investigators are displayed under the Publications heading. Some publications may not discuss the results of the study but instead provide related background information.
  • Citations automatically identified by are displayed under the heading, Additional publications automatically indexed to this study by Identifier (NCT Number).

Click on the citation to view information about the publication.

If citations are available for studies that do not have results posted on, the citations will also appear on the No Study Results Posted tab of the study record.

The example below shows the More Information section of a record with two citations: one submitted by the sponsor or investigator and one automatically indexed to the study based on its NCT Number, NCT00178100:

Search PubMed® for Results of Studies Registered on

You can also search the PubMed medical literature index for citations and abstracts of studies registered on that have results published in a medical journal. Like, PubMed is maintained by the National Library of Medicine (NLM).

If a study's NCT Number is published as part of the original journal article, the PubMed citation will include the NCT Number. See NLM's Clinical Trial Registry Numbers in MEDLINE®/PubMed® Records page for more information.

Some full-text articles are available free of charge via PubMed or PubMed Central®. Ask your local librarian about getting full-text articles through interlibrary loan.
