Xu et al. (2023) also examined the mediating role of metabolic factors, finding that higher BMI, mean arterial pressure (MAP), fasting blood glucose (FBG), total cholesterol (TC), triglycerides (TG), ALT, and AST directly contributed to NAFLD occurrence, while the indirect effects of FBG, TC, TG, ALT, and AST were not statistically significant. Here, GPT is linked to metabolic dysfunction-associated steatotic liver disease.
