*The basis for the assumed risk is the mean control group risk across studies, except for mortality at maximal follow‐up where there were no deaths; a control group proportion of 1% was used for mortality at maximal follow‐up. 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; OR: Odds 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 Downgraded one level for risk of bias because of the high risk of bias in the trial(s). 2 Downgraded one level for imprecision because of sample size. 3 Downgraded one level for imprecision because of wide confidence intervals.
