Values of BMI,waist circumference, ALT, AST, GGT, fasting blood glucose (FBG), triglyceride (TG), triglyceride (TC), HOMA-IR (CP) and HBA1C values were all higher in T2DM with NAFLD group,while creatinine (CR), CysC, high density lipoprotein (HDL) and 25-(OH) D levels were significantly lower among the T2DM combined-NAFLD group than simple T2DM group (all p < 0.05). Here, GPT is linked to metabolic dysfunction-associated steatotic liver disease.
