Computed tomography-based multi-organ radiomics nomogram model for predicting the risk of esophagogastric variceal bleeding in cirrhosis

Table 3 Area under the receiver operating characteristic curve values of different models in training and validation cohorts

Models	Training cohort		Validation cohort
	AUC (95%CI)	P value	AUC (95%CI)	P value
Rad-score (liver)	0.801 (0.727-0.875)	< 0.001	0.763 (0.646-0.880)	0.002
Rad-score (spleen)	0.831 (0.766-0.897)	< 0.001	0.792 (0.677-0.906)	0.016
Rad-score (esophagus)	0.864 (0.807-0.922)	< 0.001	0.857 (0.762-0.952)	0.109
Rad-score (liver+ spleen + esophagus)	0.930 (0.891-0.970)	0.049	0.886 (0.808-0.964)	0.139
Clinical model	0.727 (0.644-0.811)	< 0.001	0.692 (0.556-0.828)	< 0.001
RC model	0.951 (0.919-0.983)		0.93 (0.872-0.987)

P value is the results of Delong test between each model and the RC model. AUC: Area under the receiver operating characteristic curve; RC model: Radiomics-clinical model.
