There are 2 ways to find empirical articles in Medline:

One technique is to limit your search results after you perform a search:

  • Type in your keywords and click on the "Search" button
  • To the left of your results, under "Article Types," check off the types of studies that interest you

Another alternative is to construct a more sophisticated search:

  • From PubMed's (link below) main screen, click on "Advanced" link underneath the search box
  • On the Advanced Search Builder screen type your keywords into the search boxes
  • Change one of the empty boxes from "All Fields" to "Publication Type"
  • To the right of Publication Type, click on "Show Index List" and choose a methodology that interests you. You can choose more than one by holding down the "Ctrl" or "⌘" on your keyboard as you click on each methodology
  • Click on the "Search" button

Since these are published in Scholarly Journals, limit to Academic, Scholarly, or Peer reviewed articles.

Then try adding this boolean phrase to your search  empirical or study or studies.



This will help limit your results but does not guarantee that all articles will be empirical studies.
