2.2 Search strategy and data extraction
We systematically searched Medline, Embase, and Cochrane Central
Register of Controlled Trials from inception to December 2023 with the
following search terms: (”FGF21 analogue” OR pegozafermin OR
pegbelfermin OR efruxifermin) AND (”non-alcoholic hepatic steatosis” OR
steatohepatitis OR NASH OR ”fatty liver disease”). The references from
all included studies were also searched manually for any additional
studies. Two authors (M.S. and L.B.) independently extracted the data
following predefined search criteria and quality assessment. The
prospective meta-analysis protocol was registered on PROSPERO on January
15, 2024, under protocol CRD42024497414.
