Filtered Resources

Filtered resources appraise the quality of studies and often make recommendations for practice.

Systematic Reviews / Meta-Analyses

A systematic review is a comprehensive search of all of the studies, papers, research, and literature revolving around a specific question. Systematic reviews are the second-highest form of evidence because the process to develop a review requires close examination and appraisal of the studies included. Systematic reviews do not include statistical analysis.

A meta-analysis is a systematic review that combines all the results of all the studies into a single statistical analysis of results. This is the highest form of evidence as both close review and appraisal and statistical analysis are performed.

Critically-Appraised Topics & Evidence Syntheses

A critically appraised topic (or CAT) is a short summary of evidence on a topic of interest, usually focussed around a clinical question. Defined as a brief summary of the literature related to a focused clinical question (EBEM, n.d.). While the search is not comprehensive, the review of literature is followed by a critical appraisal process to assess the quality of research.

Critically-Appraised Individual Articles & Article Synopses

Authors of critically-appraised individual articles evaluate and synopsize individual research studies. Instead of conducting large reviews or writing a summary of several articles on a given topic, this approach involves a physician or researcher providing an in-depth review/analysis of one particular research article.
