Immune-related gene signature predicts the OS of patients with BLCA. (A) Receiver operating characteristic curves evaluating accuracy of the prognostic model for predicting the OS of patients from The Cancer Genome Atlas BLCA database in 1, 3 and 5 years. (B) Risk score of each patient assessed by the prognostic model. (C) Distribution of survival status scatters for patients according to the risk scores. (D) Heatmap of gene expression levels of risk genes in the prognostic model. BLCA, bladder cancer; OS, overall survival; AUC, area under the curve; EREG, proepiregulin; PNOC, prepronociceptin; MAPT, microtubule-associated protein tau; PTGER3, prostaglandin E2 receptor EP3 subtype; EGR1, early growth response protein 1; FOSL1, FOS-related antigen 1; MICB, major histocompatibility class I polypeptide-related sequence B.
