We found a tendency that the BLCA patients with gradually ascending EPDR1 expression level would have a worse status, and the results showed that clustering of patients into two groups (Fig. 3a, p < 0.05, HR (low) = 0.621) or three groups (Fig. 3b, p < 0.05) in each cohort had significant differences in OS with BLCA. This evidence concerns the gene EPDR1 and bladder transitional cell carcinoma.
