In model 4, we added ALT, AST, GGT, TC, HDL-C, LDL-C, and TG on the basis of model 3, and the probability that a patient had NAFLD increased as FT3 level elevated (OR = 1.301, 95% CI 1.028-1.645, P < 0.05). The gene discussed is GPT; the disease is metabolic dysfunction-associated steatotic liver disease.
