The search of multiple bibliographic databases retrieved
a total of 880 citations after excluding duplicate records. By
checking titles and abstracts, we found 99 records that were
potentially eligible. In addition, 15 potentially relevant
records were identified from a scoping literature review
we previously conducted and the bibliographies of included
studies. After examining the full text of 114 records, we
included 64 SRs that met the inclusion criteria
(Fig. 1).13e76 References of excluded records and reasons
for exclusion are shown in Online Appendix B.
