Legend: Hepatitis C virus (HCV); international unit per milliliter (IU/mL); Interleukin 28B (IL28B); number of patients (N); Sustained Virological Response (SVR); Positive predictive value (PPV); 95% Confidence Interval (95% CI); Matched condition (+); Unmatched condition (–). The negative condition refers to: HCV decline of <1.5 log IU/mL, baseline viral load ≥600,000 IU/mL, and IL28B Non-CC genotype. *Total population included = 148.
