Search strategy
Since there are no guidelines for assessing the prevalence of systematic
reviews studies, we followed the Preferred Reporting Items for
Systematic Reviews and Meta-analyses (PRISMA)
guidelines24 to conduct and perform this meta-analysis
and systematic review. Three medical databases (PubMed, Embase, and Web
of Science) were independently searched by two screeners (XSY and NSM)
from database inception until January 11, 2022. The details of the
search strategy are listed in Supplementary Table 1. The study protocol
was registered online at PROSPERO (ID CRD: 42022311156).
