Advanced fibrosis determines the prognosis of nonalcoholic fatty liver disease(NAFLD);therefore,accurate risk-prediction for advanced fibrosis is fundamental in the management of NAFLD(1).Targeted screening for advanced fibrosis in high-risk populations,such as those with type 2 diabetes,obesity with metabolic complications,a family history of cirrhosis,or significant alcohol use is recommended for implementing early intervention to prevent future adverse hepatic outcomes of NAFLD(2,3).Non-invasive tests including fibrosis-4 index(FIB-4)and liver stiffness measurement(LsM)are recommended to identify individuals at a higher risk of liver-related events(1,2).In addition to clinical classifications,such as FIB-4;genetic information provides further stratification for liver-related outcomes(4).
