GRADE Guidelines

GRADE provides guidance for rating the quality of evidence and the  strength of recommendations in health care.  A series of articles describing the GRADE approach were published in the Journal of Clinical Epidemiology (2011, Vol 64, Issue 4).

GRADE guidelines: 1. Introduction—GRADE evidence profiles and summary of findings tables

GRADE guidelines: 2. Framing the question and deciding on important outcomes

GRADE guidelines: 3. Rating the quality of evidence

GRADE guidelines: 4. Rating the quality of evidence—study limitations (risk of bias)

GRADE guidelines: 5. Rating the quality of evidence—publication bias 

GRADE guidelines 6. Rating the quality of evidence—imprecision 

GRADE guidelines: 7. Rating the quality of evidence—inconsistency

GRADE guidelines: 8. Rating the quality of evidence—indirectness
