Construction of a MAGs based signature to predict the prognosis of BC. a Univariate Cox regression analysis showed that five MAGs are closely associated with the OS of BC patients. b–d Kaplan–Meier curves revealed that the high-risk group had significantly shorter overall survival (OS), disease-specific survival (DSS), and progression-free interval (PFI) compared with the low-risk group. e However, the signature was not associated with disease-free interval (DFI). f ROC curves showed that the area under the curves (AUCs) of the risk score, age, gender, grade, stage, T, M, and N were 0.766, 0.549, 0.436, 0.553, 0.646, 0.623, 0.522, and 0.638. g Univariate Cox regression analysis showed that age, stage, T, N, and risk score were significantly related to the survival of BC patients. h Multivariate Cox regression analysis demonstrated that the signature could serve as an independent prognostic predictor for BC patients
