GPT and Insulin resistance: Compared with the control group, patients with NAFLD showed significantly higher levels of alanine aminotransferase (ALT), serum CK18‐M65 and CK18‐M30 levels, body mass index (BMI), homeostasis model assessment of insulin resistance index (HOMA‐IR), triglyceride (TG), total cholesterol (TC), aspartate aminotransferase (AST), and waist‐to‐hip ratio (p < 0.05).
