Table 2 The C-index of the prognostic model, TNM staging, Treatment, and EBV DNA for prediction of OS in the training cohort and validation cohort
From: Development and validation of a risk prediction score for patients with nasopharyngeal carcinoma
Factors | C-index (95% CI) | P |
|---|---|---|
For training cohort | ||
Our model | 0.733 (0.673 ~ 0.793) | |
TNM staging | 0.712 (0.657 ~ 0.768) | |
Treatment | 0.542 (0.505 ~ 0.580) | |
EBV DNA | 0.691 (0.626 ~ 0.756) | |
Prognostic model vs TNM staging | 0.531 | |
Prognostic model vs Treatment | < 0.001 | |
Prognostic model vs EBV DNA | 0.035 | |
For validation cohort | ||
