Successful eradication of recurrent hepatitis C virus (HCV) infection following liver transplantation improves graft survival. This study aimed at evaluation hepatic fibrosis changes among long-term responders to DAA therapy for HCV after using noninvasive methods. Patients with significant (≥F2) who achieved SVR12 treatment DAAs were included (n = 52).
