SLC16A3 and urinary bladder cancer: Furthermore, in the univariate Cox regression analysis, high MCT4 expression (HR: 2.024; 95% CI: 1.004–4.082; p = 0.049) and nerve infiltration (HR: 2.801; 95% CI: 1.153–6.804; p = 0.023) showed a significant influence on the OS of bladder cancer patients (Table 3).
