*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 | ||||||
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 |
The study by Smailiene et al. did not make clear some points of their assessment of risk of bias. Due to its weight in the analysis, it was classified as a serious risk of bias.
Few studies were included in the analysis; therefore, the analysis is not robust.
The analysis was composed mostly of observational studies.
Statistical heterogeneity across studies (I² between 50–80 %).
Wide confidence interval.
