Kaplan-Meier curves showed statistical difference between TSP-1-1223 A/G polymorphism and time-to-recurrence in bladder cancer (AA 20.5 months, 95% CI = 14.7 to 26.3; AG 22.2 months, 95% CI 15.6 to 28.7; GG 18.8 months, 95% CI 12.7–25.0; log-rank test, P = 0.017, Figure 2). This evidence concerns the gene THBS1 and urinary bladder carcinoma.
