Search the Cochrane LibraryWright State University does NOT currently subscribe to the Cochrane Library, so we cannot access current subscription-based content. However, the Cochrane Library is still searchable and PubMed still indexes Cochrane Reviews. Also, many Cochrane Reviews are available as open access. If you need a Cochrane Review that requires a subscription or fee, please contact your subject librarian.

Strategies for Effective Searching, Part 1 by Part 1. This strategies introduction is split into two parts. It starts with a PICO(T) question and discusses how to brainstorm synonyms and when it is appropriate for particular PICO(T) elements to be included and excluded from database searches. The videos also review the use of truncation and Boolean operators in database searches. -

Using PubMed in Evidence-Based Practice Training Course (HTML)When conducting research, evidence-based practice is a method for framing clinical questions that will help yield optimal search results. PubMed is a free research tool from the National Library of Medicine®. This course will show you how to use evidence-based practice when searching clinical questions using PubMed®.
Note: To search PubMed®, please use Wright State's link for PubMed rather than the PubMed.gov® URL. This will ensure that you can access WSU and OhioLINK subscriptions to full text articles

Selected Tools for Critical Appraisal and Grading the Strength of Evidence
Here are a few links you might find helpful for evaluating the evidence you find, but your professor may require you to use others. Please refer to your syllabus and ask your professor if you are uncertain if you need to use a particular set of critical appraisal tools. (Temple University Libraries compiled this list of tools and has a more extensive list of critical appraisal resources on its Critical Appraisal Guide).
Critical Appraisal Checklists and Worksheets for a Variety of Study Designs
Grading the Strength of Evidence
-
GRADE ApproachGRADE: (Grading of Recommendations Assessment, Development & Evaluation) The GRADE Approach is used in a systematic review to make an overall recommendation of the evidence from strong to weak.
-
GRADE CERQual(Confidence in the Evidence from Reviews of Qualitative Research): GRADE for qualitative systematic reviews to assess the evidence or develop recommendations.
-
