Table 2 showed that GSDMB was a protective factor with HR < 1, while ALDH1L2, ANXA1, CERCAM, GNA12, and PLOD1 were risk factors (HR > 1) in BLCA patients. The Kaplan-Meier survival curves confirmed that higher expression of GSDMB and lower expression of ALDH1L2, ANXA1, CERCAM, GNA12, and PLOD1 were associated with better OS in the training set (Supplementary Figure 3A–F). The gene discussed is PLOD1; the disease is bladder transitional cell carcinoma.
