Figure 2. Cumulative risk of hepatocellular carcinoma of participants stratified by their sum of risk score in high risk validation cohort.

(A) all anti-HCV seropositives (risk score <13 for low-risk, 13–18 for medium-risk, and ≥19 for high-risk group) (B) anti-HCV seropositives with detectable HCV RNA (risk score <9 for low-risk, 9–15 for medium-risk, and ≥15 for high-risk group).
