However, in another systematic review and meta-analysis implemented in 2020 with 15 clinical trials, consumption of green tea, catechin-enriched green tea, or EGCG overall exerted no significant effect on liver enzymes such as ALT (−0.17 (−0.42 to 0.08)), AST (0.07 (−0.43, 0.29)), and ALP (−0.17 (−0.45, 0.10)) (expressed as Standardized Mean Difference (95% confidence intervals), SMD (95% CI)), whereas subgroup analyses disclosed that the interventions decreased the levels of liver enzymes in participants with NAFLD while increasing liver enzymes in healthy subjects [152]. Here, GPT is linked to metabolic dysfunction-associated steatotic liver disease.
