This network meta-analysis assessed the efficacy of four distinct exercise modalities—aerobic, resistance, mind-body, and HIIT—on BMI in patients with NAFLD, alongside four lipid metabolism indicators (TC, TG, HDL-C, and LDL-C) and three liver function parameters (AST, ALT, and GGT). This evidence concerns the gene GPT and metabolic dysfunction-associated steatotic liver disease.
