" This systematic review and meta-analysis were conducted according to the criteria established by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) [] (Supplementary file). The search was carried out in the PubMed and Scopus databases. The search strategy was developed by combining the following Medical Subject Headings (MeSH) descriptors: (“aspartate aminotransferase” OR “alanine aminotransferase” OR “gamma-glutamyltransferase”) AND (“metabolic syndrome”) (Supplementary file). In addition, we included cross-sectional and longitudinal studies published between January 2017 and July 2022 that investigated the association between liver enzymes (ALT, AST, GGT) and MetS. In addition, the results had to include the mean and standard deviation. Only papers written in English and Spanish, and those that collected data from subjects over 18 years of age, were considered. The systematic review was registered in PROSPERO with ID CRD42023366810."
