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.
