Note. Rows are organized alphabetically by primary study included in each analysis. If a primary study is missing from a particular review, then EXCL = excluded; NA = not applicable because study published after review published; NI = not identified, only available when review authors reported excluded studies at full text level; otherwise, this information was “Missing.” Effect sizes and/or 95% CIs for the same outcome/trial that differ between meta-analyses appear in boldface.

WMD = Weighted mean difference effect size.

a

Appeared in “eligible for review” section but the only instance was in "Table 1. Quality of included randomized trials" and it did not appear in any meta-analyses.

b

missing r – calculated.

c
