PubMed includes over 28 million citations for biomedical articles dating back to the 1950s. PubMed includes articles from MedLine, PubMed Central, Life Science Journals, and e-Books. Citations may include full-text links from PubMed Central or the Publisher websites; if the full-text is unavailable try searching for the Journal with Speed Library's Journal Finder.
Use MeSH (Medical Subject Headings) to conduct a more streamlined and complete search in PubMed. Include MeSH terms in your search via the MeSH database or including "term" [MeSH] in your search query.
Use Clinical Queries to limit to clinical study categories, systematic reviews (description), or medical genetics. These pre-filtered searches follow evidence-based practice and are more narrow in scope. For a comprehensive search on a topic, use the traditional PubMed searching feature. The link to Clinical Queries is under PubMed Tools on the PubMed home page.
When searching the full PubMed, use Filters to target retrieval. Filtering your results to Date, Language, Age, and Species will significantly reduce the number of citations, for the comprehensive list of filters select Show Additional Filters on the left-hand column. Filtering to Type of Article (meta-analyses, RCTs) is an effective way to retrieve the highest Levels of Evidence.
