Cumulative incidence of hepatocellular carcinoma (HCC) according to post-treatment WFA+-M2BP values.
Cumulative incidences of HCC according to post-treatment WFA+-M2BP values were analyzed using the Kaplan-Meier method. The black solid and dotted lines indicate the stratified post-treatment WFA+-M2BP values with a COI ≤ 2.0 and a COI > 2.0, respectively. The incidence rate differed significantly between the two groups (P < 0.0001 by the log-rank test). The numbers of patients at risk at each time point are shown below the graphs.
