Evaluating the prediction performance of the risk model. A, B Univariate and multivariate Cox analyses were performed to verify the effect of DEMs on OS; HR > 1 was a risk factor, HR < 1 was a protective factor, and P < 0.05 was chosen as the screening threshold; C-E Validating the prognostic prediction ability of risk model; the distribution of OS status in high-risk and low-risk breast cancer patients were presented in dot-plot (C); KM survival analysis assessed OS differences in high-risk and low-risk patients (D); ROC curves was applied to compare the sensitivities and specificities of BC risk model in 1, 3, and 5 years (E)
