Multicenter Validation Study of a Diagnostic Algorithm to Detect NASH and Fibrosis in NAFLD Patients With Low NAFLD Fibrosis Score or Liver Stiffness.

Objectives: Nonalcoholic steatohepatitis (NASH) and fibrosis play critical roles for the prognosis of patients with nonalcoholic fatty liver disease (NAFLD). Identification of patients at risk of NASH and fibrosis is therefore critical for disease management. NAFLD Fibrosis Score (NFS) and transient elastography (TE) have been suggested to exclude advanced fibrosis.
