Table 3.
Results of Cox regression analysis on all MIBC patients stratified into three groups (II, III and IV) using the standard TNM staging and the proposed model respectively, with their respective stage II as reference.
Model | Cox regression | Likelihood ratio test | Wald test | Log rank test | ||
---|---|---|---|---|---|---|
Factor | HR [95% CI] | p value/q value | ||||
Clinical TNM staging | Stage III | 1.92 [0.82 4.51] | 0.13 | G = 34.1 p = 3.94E−08 | z2 = 36.2 p = 1.41E−08 | lr = 44.95 p = 1.74E−10 |
Stage IV | 8.66 [3.65 20.28] | 8.4E−07** | ||||
TB stage model | Stage III | 2.48 [1.18 5.21] | 0.017*/0.119 | G = 36.9 p = 9.78E−09 q = 6.85E−08 | z2 = 37.83 p = 6.09E−09 q = 4.26E−08 | lr = 47.35 p = 5.22E−11 q = 3.65E−10 |
Stage IV | 7.33 [3.87 13.89] | 1.0E−09**/7.0E−09 |
Two degrees of freedom are considered for overall tests. P values of the TB stage model are corrected (q values) for multiple hypothesis testing corresponding to the (m = 7) features used for TB quantification.
