Cumulative incidence rates of death for the five risk groups in the development cohort.

<p>Groups were divided by quintiles of risk probability, in which the med-low / med / med-high / and highest risk groups had 2.17 (95% Confidence Interval [CI]: 1.70–2.78) / 4.83 (95% CI: 3.84–6.08) / 11.27 (95% CI: 8.99–14.14) / and 26.56 (95% CI: 21.07–33.48) -fold higher incidence of hepatocellular carcinoma compared to the lowest risk group, respectively.
