2-year DFS Kaplan-Meier curves of HCC patients. (A) 2-year DFS Kaplan-Meier curve in the training group (N = 112), the recurrence probability was higher in the high-risk group than that in the low-risk group (P < 0.0001); (B) 2-year DFS Kaplan-Meier curve in the validation group (N = 111), the recurrence probability was higher in the high-risk group than that in the low-risk group (P = 0.033); (C) 2-year DFS Kaplan-Meier curve in the entire TCGA group (N = 223), the recurrence probability was higher in the high-risk group than that in the low-risk group (P < 0.0001). Statistical significance was tested by the Log-rank method
