Study flow. Sixty patients with chronic hepatitis C were enrolled in this study. Of these, 59 completed treatments, with 1 discontinuation due to suspected pregnancy (who nevertheless achieved SVR12). Two patients were lost to follow-up. The remaining 57 patients were included in the per-protocol analysis, comprising 22 patients who attended ≥ 4 visits before SVR12 and 35 patients who attended ≤ 3 visits.
