Moreover, this index showed the highest AUROC compared to AST/ALT ratio and FIB-4 for the detection of any grade of liver fibrosis and superior AUROC than AST/ALT ratio but similar AUROC to FIB-4 for distinguishing between F3/F4 and F0-F2 of liver fibrosis in these patients. The gene discussed is GPT; the disease is Hepatic fibrosis.
