*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% CI) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI). |
1The risk in the control arm was 0% so low risk of 1% and high risk of 10% assumed. 2 Downgraded due to one small study at high risk of bias.
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.
