Appendix Figure 1: Flow diagram of study selection

* Many of the handsearch abstracts turned out to be duplicates, since the handsearch titles were not fully deduplicated prior to reviewing. Seven original nonduplicated studies from the handsearch met the full inclusion criteria.

† Reviewers were allowed to list multiple reasons for exclusion at the abstract level; therefore, the numbers of exclusions are higher than abstracts excluded

‡Reviewers were instructed to list only one reason for exclusion, but sometimes reviewers listed more than one reason for exclusion at the article review level; therefore, the number of reasons for exclusions exceed the number of articles excluded

¶ N of studies in parenthese are N of studies included in the meta-analyses when meta-analyses were conducted if the N of studies differed from the original N of studies included

*The Jadad quality score is continuous and ranges from 0 to 5, with 5 being the highest quality. Columns are scored as 1 point if “yes” and 0 points if “No” or “NR”. For the starred columns (randomization appropriate and double blinding appropriate), an additional point is given if “Yes” is marked and a point is deducted if “No” is marked.
