PubMed @ UMSL

For each citation, PubMed provides a link to Similar articles. By default, it provides five articles, but you can expand the list to Show more or See all.

The filters you selected for your primary search will be retained when viewing similar articles. Clear the filters to expand the search even further.

When the citation you're viewing has been cited by others, you can follow the citation trail to locate other articles on the subject. 

To expand your results using Boolean operators, try adding synonyms/related terms with OR (in capital letters): for example, (marijuana OR cannabis) AND (academic performance OR grades). The parentheses in this search clarify we still have 2 concepts, and both must be present. Please speak with a Reference Librarian if you need help combining search terms with Boolean operators.

• Look for misspellings in your search terms.
• Decrease the number of concepts searched.
• Try a broader search term.
• Remove terms that are unlikely to be used by an author.
• Replace terms that are too specific.
• Increase the number of synonyms or alternatives for a term.
• Use a truncation symbol at the end of a term to pick up variant endings (see the Basic Search section).
• Try the same search(es) in different databases.
• Ask for significant words to be in the full text of the article (field searching).
• Check for missing or incorrect field qualifiers.
