GPT and fatty liver disease: Unique selection strategies were compared to determine the best screening algorithm: (A) A “metabolic approach”: selecting patients based on HOMA-IR ≥ 3; (B) A “diabetes approach”: selecting only patients with type 2 diabetes; (C) An “imaging approach”: selecting patients with hepatic steatosis based on 1H-MRS; (D) A “liver biochemistry approach”: selecting patients with elevated ALT (i.e., ≥ 30 IU/L for males and ≥ 19 IU/L for females); and (E) Universal screening of overweight and obese patients.
