"This study reported in accordance with the Preferred Reported Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines (Supplementary Table S1). Two of the reviewers (C.Y. Leung and H.L. Huang) systematically searched PubMed, Embase, and Cochrane Library for articles published in peer-reviewed journals, from inception to April 20, 2022, using keywords relating to MHT, pancreatic cancer, and risk. We applied no language restrictions. Only studies provided relative risks (RR) with 95% confidence intervals (CI) or provided sufficient data that allow risk estimates to be computed were eligible for inclusion. Preestablished review protocol was registered in PROSPERO (CRD42022327363). Details of the search strategies are described in Supplementary Tables S2–S4."
