Construction of risk signature in the TCGA cohort. A Univariate Cox regression analysis for screening the survival-related pyroptosis genes. B Distribution of patients based on the risk score in the TCGA cohort. C The survival status for each patient in the TCGA cohort (low-risk population: on the left side of the dotted line; high-risk population: on the right side of the dotted line). D Kaplan–Meier curves for the OS of patients in the low-risk group and high-risk group in the TCGA cohort. E ROC curves demonstrated the predictive efficiency of the risk score in the TCGA cohort
