(A) Kaplan–Meier analysis of OS in the basal-like carcinoma group: OS rates between the high-risk group and low-risk group showed statistically significant differences using the log-rank test (P=0.003); (B) the ROC curve AUC was 0.755. (C) Kaplan–Meier analysis of OS in the luminal carcinoma group: OS rates between the high-risk group and low-risk group showed statistically significant differences using the log-rank test (P<0.0001); (D) the ROC curve AUC was 0.688. (E, F) Kaplan–Meier analysis of OS in the Her2-enriched subgroup showed no significant differences between the high-risk group and low-risk group; the AUC and P-value were 0.545 and 0.5532, respectively. This signature showed better performance in basal-like and luminal patients than in Her2-enriched patients.

Abbreviations: AUC, area under the curve; OS, overall survival; ROC, receiver operating characteristics.
