Look for these headings to help you determine if an article is original research. While primary research articles usually start with a brief literature review of previous and similar research, the rest of the article focuses on the authors' original research.

If you are looking for a specific population or age group there are filters for those as well.
Important! From your list of results, you will still need to examine each article to see if it is primary research and not a synthesis of others' research.
