CALU and bladder transitional cell carcinoma: Subsequent multivariate cox regression analysis suggested that CALU (p=0.0021, HR=1.335, 95%CI:1.111-1.605), age (p=0.0001, HR=1.032, 95%CI:1.017-1.048) and stage (p=0.0001, HR=1.534, 95%CI:1.24-1.897) could be used as independent risk factors for BLCA prognosis.
