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

CI: confidence interval;MD: mean difference;RR: risk ratio
GRADE Working Group grades of evidence
High certainty: we are very confident that the true effect lies close to that of the estimate of the effect.
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.
Low certainty: our confidence in the effect estimate is limited: the true effect may be substantially different from the estimate of the effect.
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.
Explanations
a. Downgraded by one for limitation in study design (High RoB)
b. Downgraded by one for imprecision (small sample size)
