How to Browse for Studies by Topic

Select See Studies by Topic from the Find Studies menu or click on See Studies by Topic on the home page or at the top of any page on ClinicalTrials.gov to browse for studies using any of the following topics:

  • Conditions
  • Rare diseases
  • Drug interventions
  • Dietary supplements
  • Sponsor/collaborators (for example, National Heart, Lung, and Blood Institute (NHLBI))
  • Locations (for example, United States, New York)

Within these topics, you can browse by using an alphabetical (A–Z) list or a list organized by category. The Rare Diseases topic is only alphabetical and the Locations topic includes a list by region instead of by category.

Practice

  • Select See Studies by Topic from the Find Studies menu or click on See Studies by Topic on the home page or at the top of any page on the site.
  • Under Conditions, click on By Category to see the list of condition categories.
  • Click on Cancers and Other Neoplasms to see a list of types of cancers and neoplasms.
  • Click on Breast Neoplasms to see a search results list of all studies involving breast neoplasms (breast cancer).

The first column of the search results list, Rank, indicates the order in which the studies are listed. Studies that most closely match your search terms are listed first. The Status column shows which studies are open, or recruiting new volunteers, and which studies are closed, or not recruiting new volunteers.

The subcategory words will be highlighted in the text of each of the study records found by your search. Subcategory words will be highlighted in pink, and synonyms for subcategory words will be highlighted in yellow. For example, the words "breast" and "neoplasms" will be highlighted in pink wherever they appear in each record. Synonyms for breast neoplasms, such as breast cancer, will be highlighted in yellow.
