Kaplan-Meier estimates of the disease free survival (DFS) of patients using the seven-lncRNA signature, stratified by KRAS mutation status. Entire GSE39582 dataset were first stratified by KRAS mutation status (WT or Mutation) and Kaplan-Meier plots were then used to visualize the survival probabilities for patients within each stratum. a Kaplan-Meier curves for the entire GSE39582 dataset patients (N = 536); b Kaplan-Meier curves for patients with wide-type KRAS gene (WT, N = 322); c Kaplan-Meier curves for patients with mutated KRAS gene (Mutation, N = 214). The tick marks on the curves represent the censored events. The differences between the two curves were determined by the two-sided log-rank test. d The ROC curves of seven-lncRNA risk score (blue) and KRAS mutation (red) were shown in entire GSE39582
