**Figure 8.** **Predictive nomogram for PRS and clinical features.** (**A**) The 15 pyroptosis-related prognostic model for predicting 3-, 5-, and 7-year OS in BC patients. The independent risk factors were used to build a risk estimation nomogram to predict the probability of OS in BC patients. (**B**) The calibration plots for 3-year survival probabilities in the TCGA cohort. (**C**) The calibration plots for 5-year survival probabilities in the TCGA cohort. (**D**) The calibration plots for 7-year survival probabilities in the TCGA cohort.
