*The basis for the assumed risk (e.g. the median control group risk across studies) is provided in footnotes. The corresponding risk (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; RR: Risk ratio;
GRADE Working Group grades of evidence
 High quality: Further research is very unlikely to change our confidence in the estimate of effect.
 Moderate quality: Further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate.
 Low quality: Further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate.
 Very low quality: We are very uncertain about the estimate.

1 Assumed risk: mean baseline risk from single study.
 2 Imprecision: rated 'serious' ‐ confidence intervals for best estimate of effect include both 'no effect' and appreciable benefit/harm; high degrees of heterogeneity (I2 = 59%).
 3 Risk of bias: rated 'serious' ‐ no mention of randomisation procedure; unreported outcomes of interest; involvement by pharmaceutical company.
 4 Assumed risk: 'moderate' equates to that of control group. Low, moderate and high risks calculated from included studies.
