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

CI: confidence interval; RCT: randomised controlled trial; RR: risk ratio

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.
Moderate quality: 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 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.

1Downgraded by one level due to imprecision (< 300 events). We decided not to downgrade for risk of bias as out of four studies, the largest three were judged to be at low risk of bias.

2Downgraded by one level due to imprecision (< 300 events). We decided not to downgrade for risk of bias as both studies were judged to be at low risk of bias.

3We decided not to downgrade for risk of bias as out of four studies, the largest three were judged to be at low risk of bias. We also decided not to downgrade for inconsistency as removing one outlier eliminated inconsistency but hardly affected pooled estimate.

4We decided not to downgrade for risk of bias as all three studies were judged to be at low risk of bias.

5Downgraded by one level due to imprecision (< 300 events). We decided not to downgrade for risk of bias as all three studies were judged to be at low risk of bias.
