Adverse effects | ‐ | ‐ | ‐ | No studies measured adverse effects. |
*The risk in the intervention group (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; MD: mean difference; RCT: randomised controlled trial | ||||
GRADE Working Group grades of evidence High certainty: We are very confident that the true effect lies close to that of the estimate of the effect. Moderate certainty: We are moderately confident in the effect estimate: the true effect is likely to be close to the estimate of the effect, but there is a possibility that it is substantially different. Low certainty: Our confidence in the effect estimate is limited: the true effect may be substantially different from the estimate of the effect. Very low certainty: We have very little confidence in the effect estimate: the true effect is likely to be substantially different from the estimate of effect. |
1Downgraded one level for inconsistency due to wide variance of point estimates across studies (high heterogeneity). 2Downgraded one level for imprecision due to wide confidence intervals. 3Downgraded two levels for imprecision due to very small sample sizes.
