Multivariate progression and survival analysis in patients with bladder cancer.

*Variables include the following (see Tables S6–S7 in File S4 for complete multivariate analysis): Stage: Ta-T1 vs. T2–T4 (CNUH, Dyrksjot - DSS, Lindgren, and MSKCC) and T1 vs. Ta (Dyrskjot -PFS); Grade: high vs. low (CNUH, Lindgren, Blaveri, MSKCC); high vs. low vs. PUNLMP (Dyrskjot). Surgery: cystectomy vs. transurethral resection of the bladder. Abbreviations: PFS, progression-free survival; OS, overall survival; DSS, disease-specific survival. †Final model is constructed from forward step-wise regression of significant variables (P<0.05).
