Literature search
PubMed, MEDLINE, Web of Science, EMBASE and Cochrane Register of
Controlled Clinical Trials (CENTRAL) were searched to obtain articles
addressing the effect of acupuncture on the outcomes of IVF-ET published
up to 6 September 2021. Medical Subject Headings (MeSH) terms and free
text terms were combined to screen for potentially relevant studies in
PubMed, the detailed search algorithm will be slightly modified and used
in several other databases (Appendix S1). In addition, some Chinese
databases such as the Wanfang Databases, Chinese National Knowledge
Infrastructure (CNKI), the VIP databases and SinoMed were used to
collect related studies in China.
Other potentially relevant papers were also identified by
cross-referencing. The present study complied with the preferred
reporting items for systematic reviews and meta-analyses (PRISMA)
guidelines 6 (Table S1 ).
