aFor systematic reviews that used GRADE to assess the quality of the body of evidence for critical or important outcomes, the number of outcomes assessed as high, moderate, low or very low certainty of evidence is presented.
Only 20 out of the 301 included systematic reviews assessed the certainty of the body of evidence. We would like to point out that when reporting results for the GRADE assessments, these assessments are made at the level of individual outcomes, and some included reviews may thus contribute more than one assessment.
