Medical Subject Headings (MeSH terms) are categories applied by the National Library of Medicine to describe what medical publications are about.
Using them can help you focus your database search to articles that address your research topic. This video from the UAB Lister Hill Library shows how to choose MeSH terms in PubMed.
Search more effectively and efficiently by using the tools and limiters that are part of each database, including these:
Publication Date: When doing research for EBM, you usually limit your search to articles from the last 3-5 years.
Publication Type: Limit your search to certain kinds of articles or research. Other options besides those shown here include comparative studies, systematic reviews, and randomized controlled trials.
Reviews: These present authors' findings after they have reviewed multiple previously-published research articles and can provide valuable information about trends in a field.
Age Groups: Limit by patient characteristics including age and sex.
