The point estimate for the difference in SVR and its respective credible interval (CI) were evaluated at 24 weeks off of planned treatment for both arms. The comparison of efficacy is between treatment durations and timepoint corresponds to Week 72 in Arm 1 and Week 60 in Arm 2. 95% CI refers here as credible interval.
