Efficacy of direct-acting antiviral treatment for chronic hepatitis C: A single hospital experience

Figure 1 SVR rates for NS5A resistance-associated substitutions and each interferon-free agent. The number above each column is the number of cases with SVR (numerator) and total cases (denominator). Two relapsed patients with wild-type Y93, 1 with Y93 hetero and 3 relapsed patients with wild-type L31 were treated with DCV/ASV. Another 6 patients that failed to achieve SVR with DAA treatment had not obtained NS5A RASs prior to treatment. Another patient had no relapse regardless of the presence or absence of RASs. DAA: Direct-acting antivirals; DCV/ASV: Daclatasvir/asunaprevir; RAS: Resistance-associated substitution; SVR: Sustained virologic response.
