HEPATITIS MONTHLY, vol.17, no.12, 2017 (SCI-Expanded)
Background: Manynoninvasive methods, including aspartateaminotransaminase (AST)/alanineaminotransaminase (ALT) ratio (AAR), AST-to-platelet ratio index (APRI), Bonacini cirrhosis discriminant score (CDS), fibrosis-4 (FIB4) index, and age-platelet index (API), have been described to determine the stage of hepatic fibrosis. However, thesemethodsare developed for patients with chronic hepatitisC(CHC) andproduce conflicting results in the prediction of liver fibrosis in patients with chronic hepatitis B (CHB).
