While no factors predicted SVR in acute HCV and chronic HCV-2/3 infection, age (odds ratio [OR] per 1-year increase: 0.88, 95% confidence interval [CI]: 0.78–0.99, p = 0.04), HCV RNA (OR per 1-log10 increase: 0.18, 95% CI: 0.03–0.98, p = 0.03), IL28B genotype (OR: 5.52, 95% CI: 1.55–12.2, p = 0.02), and RVR (OR: 9.62, 95% CI: 3.89–15.3, p = 0.007) predicted SVR in chronic HCV-1/6 infection. Here, IFNL3 is linked to infection.
