GPT and metabolic dysfunction-associated steatotic liver disease: However, in female patients, BMI (OR, 1.651; 95% CI, 1.365–1.996; p < 0.001) and ALT level (OR, 1.104; 95% CI, 1.061–1.148; p < 0.001) were found to be two independent risk factors for NAFLD, and age was no longer found to be an independent risk factor for NAFLD.
