Kaplan-Meier analysis of the association of the 25-lncRNA risk signature with early recurrence risk in HCCs. A-C) The association of the 25-lncRNA risk signature with 2-year DFS was analyzed in the training cohort (N = 150, P < 0.0001) (A), validation cohort (N = 149, P = 0.0132) (B), and the entire TCGA cohort (N = 299, P < 0.0001) (C). The statistical significance was determined by the log-rank test. The patients in each cohort were stratified into the high-risk and low risk groups based on the cut-off risk score in the training cohort
