Prediction for early recurrence of intrahepatic mass-forming cholangiocarcinoma: quantitative magnetic resonance imaging combined with prognostic immunohistochemical markers

Table 5 Predictive performance of three models

Model	Accuracy (95%CI)	Sensitivity	Specificity	PPV	NPV	AUC (95%CI)	P value
Model	Accuracy (95%CI)	Sensitivity	Specificity	PPV	NPV	AUC (95%CI)	1 vs 2	2 vs 3	1 vs 3
1 Combined model	0.872 (0.743–0.952)	0.938	0.839	0.750	0.963	0.949 (0.894–1.000)	0.247	0.321	0.009*
2 Radiomics model	0.809 (0.667–0.909)	0.875	0.774	0.667	0.923	0.889 (0.783–0.996)
3 CRP model	0.702 (0.551–0.827)	0.813	0.645	0.542	0.870	0.798 (0.660–0.937)

Note: The number 1 indicates the combined model, 2 indicates the radiomics model, and 3 indicates the CRP model. Comparisons of the AUC between the three models were made using the Delong test. CRP clinicoradiologic-pathologic; combined model, radiomics and CRP model, AUC area under the curve, CI confidence interval, PPV positive predictive value, NPV negative predictive value, *, P < 0.05
