*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: Relative risk | ||||||
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 Control group risk estimates come from control arm of meta‐analysis, based on included trials. 2 Downgraded one level due to sparse data (153 events). 3 Downgraded two levels due to very sparse data (26 events). 4 Downgraded one level due to sparse data (271 events). 5 Downgraded two levels due to very sparse data (9 events).
