The table shows the number of studies reporting each outcome and the corresponding number of participants in these studies.
*Weights from random effects analysis. Results without indicator are from fixed-effect analysis with inverse variance weighting.
†No CIs computed because of 0 variance in all four studies reporting the outcome.
