  • GRADE Working Group grades of evidence:

  • High quality: we are very confident that the true effect lies close to that of the estimate of the effect.

  • Low quality: our confidence in the effect estimate is limited. The true effect may be substantially different from the estimate of the effect.

  • Very low quality: we have very little confidence in the effect estimate. The true effect is likely to be substantially different from the estimate of effect.

  • *The risk in the intervention group (and its 95% CI) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI).
