Univariate and multivariate Cox proportional hazard regression analyses were conducted to successively analyse the prognostic value of differentially expressed lncRNAs that identified six lncRNAs (MEG8, NAV2-AS2, STEAP3-AS1, GLIS3-AS1, LINC00158, AC012640.1) as independent risk factors for recurrence-free survival of bladder cancer patients. This evidence concerns the gene NAV2 and urinary bladder carcinoma.
