BackgroundLiver biopsy is the criterion standard to assess liver fibrosis in patients with nonalcoholic fatty liver disease (NAFLD), which is important for prognosis, whereas noninvasive scoring systems showing promise for predicting fibrotic status include aspartate/alanine aminotransferase (AST/ALT) ratio, BARD score, fibrosis–4-score (FIB-4), and the NAFLD Fibrosis Score (NFS).ObjectivesTo determine the accuracy of noninvasive scoring systems to predict advanced fibrosis in Thai patients with NAFLD.MethodsA prospective cross-sectional study of Thai patients with liver biopsy-proven NAFLD during January 2009-October 2012 at King Chulalongkorn Memorial Hospital, Bangkok, Thailand.
