Reference comparator

  1. *The risk of intervention group (and 95% confidence interval) is based on the assumed risk of the comparator group and the relative effect of the intervention (and 95% confidence interval)
  2. CI confidence interval, RR risk ratio
  3. GRADE working group grades of evidence
  4. High certainty: we are very confident that the true effect lies close to that of the estimate of the effect
  5. Moderate certainty: we are moderately confident in the effect estimate: the true effect is likely to be close to the estimate of the effect, but there is a possibility that it is substantially different
  6. Low certainty: our confidence in the effect estimate is limited: the true effect may be substantially different from the estimate of the effect
  7. Very low certainty: we have very little confidence in the effect estimate: the true effect is likely to be substantially different from the estimate of effect
