Validation of the IRGP signature using GSE31684. The score of included IRGPs in different groups (A). The categorization of BC patients into different groups (B). The survival status of patients in the high-risk group and low-risk group (C). The AUC of the ROC curve results showed a moderate prognostic power of the risk score (D). The results of Kaplan-Meier survival analysis revealed that a high-risk score was significantly related to poor OS (E). Univariate and multivariate Cox regression analyses demonstrated that the risk score was an independent prognostic factor (F-G). BC, bladder cancer; IRGPs, immune-related gene pairs; AUC, area under the curve; ROC, receiver operating characteristic; OS, overall survival
