Two liver steatosis prediction tools could help clinicians in deciding whether a patient should undergo further diagnostic assessment: (1) hepatic steatosis index (HSI), which is based on alanine aminotransferase, aspartate aminotransferase, body mass index (BMI), diabetes, and sex and was derived from a Korean cohort undergoing a health check-up; (2) fatty liver index (FLI), which is based on BMI, waist circumference, gamma-glutamyl transferase, and triglycerides and was developed in a sample with suspected liver disease and matched controls in Italy [10, 11]. Here, GPT is linked to fatty liver disease.
