Filtered resources

Filtered or secondary sources are summaries and analyses of the evidence derived from and based on primary sources (unfiltered). They provide an appraisal of the quality of studies and often make recommendations for practice.

What kinds of studies are relevant?

  • Clinical Practice Guidelines
  • Meta-Analyses
  • Systematic Reviews
  • Critically-Appraised Topics
  • Critically-Appraised Individual Articles

Search Tip: to limit a search to filtered sources, try adding a search line limited to the Title field > review OR meta

Clinical practice guidelines "are designed to support the decision-making processes in patient care . The content of a guideline is based on a systematic review of clinical evidence - the main source for evidence-based care".
