There are lots of tools available to help you critically appraise the literature you find. See below for a sample; pick the ones that work best for you.

  • Joanna Briggs Institute Critical Appraisal Tools: checklists for various study types, in both PDF and DOC formats
  • NYU: list of different resources, including critical appraisal worksheets from CEBM
  • Temple: provides a lot of info about critical appraisal and links to checklists by study type
  • GRADE: working group that created criteria for judging quality of RCTs, systematic reviews, and other evidence
  • CASP asks three questions:
  1. Is the study valid?
  2. What are the results (if the study is determined to be valid)?
  3. Are the results useful (and applicable to your patient)?

You may want to check this book out before you graduate. However, once you leave Pitt you can access it through your local public library. (If they don't have it, investigate their interlibrary loan program.)

Retraction Watch Logo




Retraction Watch is a website that features news on research misconduct, scientific controversies, and, of course, retractions. Reading it regularly will also help you to see what you should be on the lookout for when reading research. You can also sign up for the RW Daily to keep abreast of the latest retraction news.

Retraction Watch also has a database, where you can search for retracted articles by title, author, subject, reason for retraction, and much more. If you're unsure about an article, you can always look it (or the authors) up in the database.
