Study Selection
After combining articles from the three databases and removing duplicates, five reviewers (SL, SR, YJ, DN, MLW) independently screened all results with titles and abstracts. Disagreements were resolved by discussion among all five reviewers to reach consensus. After the screening, eligibility was checked with full text by five reviewers (SL, SR, YJ, DN, MLW), who each reviewed one fifth of the total articles and cross-reviewed another one fifth. Disagreements were resolved by discussion to reach consensus.
