Simultaneously searches evidence-based sources of systematic reviews, practice guidelines, and critically-appraised topics and articles -- including most of those listed above and many more. Also searches MEDLINE’s Clinical Queries, medical image databases, e-textbooks, and patient information leaflets. Free resource.
Authors of a systematic review ask a specific clinical question, perform a comprehensive literature search, eliminate the poorly done studies and attempt to make practice recommendations based on the well-done studies. A meta-analysis is a systematic review that combines all the results of all the studies into a single statistical analysis of results.
Consists of detailed, structured topic reviews of hundreds of articles. Teams of experts complete comprehensive literature reviews, evaluate the literature, and present summaries of the findings of the best studies. Published by the International Cochrane Collaboration. Click on "Cochrane Reviews"
Systematic Reviews are also searchable in these sources:
- CINAHL * : Enter your search query. Select “Systematic Reviews” under “Publication Type”
- Database of Abstracts of Reviews of Effects (DARE)
- PubMed Clinical Queries * : Enter your search query. Results will display under "Systematic Reviews"
Authors of critically-appraised topics evaluate and synthesize multiple research studies.
National Guideline Clearinghouse (sponsored by the United States DHHS)
A comprehensive database of evidence-based clinical practice guidelines and related documents produced by the Agency for Health Care Research and Quality, in partnership with the American Medical Association and the American Association of Health Plans. Updated weekly.
Note: Guideline evidence varies from expert opinion to high levels of evidence.
Authors of critically-appraised individual articles evaluate and synopsize individual research studies.
The editors of this journal screen the top 100+ clinical journals and identify studies that are methodologically sound and clinically relevant. An enhanced abstract, with conclusions clearly stated, and a commentary are provided for each selected article.
Evidence is not always available via filtered resources. Searching the primary literature may be required.

- Enter your search term(s).
- Results will display under Clinical Study Categories, Systematic Reviews, Medical Genetics.
- For Clinical Study Categories :
- you can filter by "category" (etiology, diagnosis, therapy, prognosis, clinical prediction guidelines) or
- "scope" (broad or narrow)
- For Medical Genetics :
- you can filter by "topic" (diagnosis, differential diagnosis, clinical description, clinical description, management, genetic counseling, molecular genetics, genetic testing)
