Prognostic significance of alternative polyadenylation subtype in triple-negative breast cancer. (A) Kaplan-Meier survival curves of disease-free survival (DFS) among the alternative polyadenylation (APA) subtypes. (B) Comparison of the area under the curve (AUC) of time-dependent receiver operating characteristic (ROC) curves with two Cox proportional-hazards models. blue: lymph node; red: lymph node + APA subtype. Data are shown as mean ± standard error. *p < 0.05, **p < 0.01. Abbreviations: APA, alternative polyadenylation; AUC, area under the curve; DFS, disease-free survival; ROC, receiver operating characteristic.
