*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 Failure to adherence to intention‐to‐treat principle. Selective reporting. Stopping early for benefit. 2 Large variation in effect. Confidence intervals overlap.Substantial heterogeneity. 3 Few women and outcome events. Confidence interval include null effect, include appreciable harm or benefit. Not optimal information size. 4 Lack of blinding. Failure to adherence to intention‐to‐treat principle. Selective reporting. Stopping early for benefit. 5 Large variation in effect. Confidence intervals do not overlap. Substantial heterogeneity. 6 Few women. Confidence interval includes null effect, include appreciable harm or benefit. Not optimal information size.
