Multiple databases were searched to identify relevant studies. Standardized mean differences (SMDs) with 95% confidence intervals (CIs) were calculated using random-effects models. Prespecified subgroup analyses were performed based on species, dose, and treatment duration, and sensitivity analyses assessed the robustness of the results.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Eight studies were included. 6-Gingerol significantly improved anthropometric indices, hepatic and circulating lipid profiles, liver enzymes, and glucose metabolism parameters. Beneficial effects were also observed for inflammatory mediators and adipokines in a subset of studies. Despite moderate to high heterogeneity, favorable effects were observed across the evaluated major outcome domains. Exploratory subgroup analyses suggested that treatment duration, dose, and species may contribute to between-study variability; however, the small number of studies within several subgroup strata precluded firm conclusions regarding effect modification. Sensitivity analyses showed that the overall direction of the pooled estimates was not materially changed by removal of individual studies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>6-Gingerol was associated with favorable changes in several metabolic and hepatic outcomes in animal models of NAFLD. However, these findings should be interpreted cautiously because of the limited number of studies, substantial heterogeneity, and incomplete methodological reporting.
