Comparison of diagnosis efficacy of the model.
| Group | Model | C_index (95% CI) | Likelihood value | P |
|---|---|---|---|---|
| Training group | Radiomics model | 0.714 (0.581–0.848) | −47.78 | .014 |
| Clinical model | 0.59 (0.423–0.758) | −46.24 | .019 | |
| Nomogram model | 0.812 (0.707–0.917) | −43.471 | — | |
| Validation group | Radiomics model | 0.751 (0.58–0.922) | −34.28 | .256 |
| Clinical model | 0.585 (0.431–0.739) | −37.58 | .002 | |
| Nomogram model | 0.725 (0.556–0.895) | −32.92 | — |
CI = confidence interval.
P refers to the comparison between Nomogram model and Clinical model/Rad_score model.
