Kaplan-Meier estimates of the disease free survival (DFS) of patients using the seven-lncRNA signature, stratified by adjuvant chemotherapy. Entire GSE39582 dataset were first stratified by chemotherapy (with or without) 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 = 541); b Kaplan-Meier curves for patients with adjuvant chemotherapy (N = 232); c Kaplan-Meier curves for patients without adjuvant chemotherapy (N = 309). 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 chemotherapy (red) were shown in entire GSE39582
