Evidence-Based Searching

Finding the Best External Evidence

PubMed®’s “Clinical Queries” page provides links to specialized searches:

Search by Clinical Study Category allows you to focus your search on:

  • etiology,
  • diagnosis,
  • therapy, or
  • prognosis

And you can also specify two levels of retrieval:

  • narrow, specific search or
  • broad, sensitive search

Find Systematic Reviews allows you to restrict retrieval to the following group of publication types:

  • systematic reviews
  • meta-analyses
  • reviews of clinical trials
  • evidence-based medicine
  • consensus development conferences
  • guidelines

Medical Genetics Searches limits retrieval to various topics in medical genetics.
