Kaplan-Meier estimates of disease-free survival for estrogen receptor-beta (ER-β) status within the molecular subtypes. Kaplan-Meier estimates of disease-free survival for estrogen receptor-beta (ER-β) status within the molecular subtypes and according to negative (N-) or positive (N⁺) nodal status, respectively, in each subgroup: luminal A (LA) (a, e), luminal B (LB) (b, f), HER2 (HS) (c, g), and triple-negative (TN) (d, h). P values were calculated using the log-rank test.
