Dual-modal radiomics nomogram based on contrast-enhanced ultrasound to improve differential diagnostic accuracy and reduce unnecessary biopsy rate in ACR TI-RADS 4–5 thyroid nodules

Table 6 Comparison of the AUCs for three different models in the training, validation, and entire cohorts

	Training cohort		Validation cohort		Entire cohort
	AUC	P value	AUC	P value	AUC	P value
Dual-modal US radiomics nomogram vs. Clinical combined with US model	0.873 vs. 0.815	0.032	0.851 vs. 0.770	0.047	0.867 vs. 0.801	0.003
Dual-modal US radiomics nomogram vs. Dual-modal US Rad-score	0.873 vs. 0.802	0.006	0.851 vs. 0.808	0.196	0.867 vs. 0.803	0.002
Clinical combined with US model vs. Dual-modal US Rad-score	0.815 vs. 0.802	0.773	0.770 vs. 0.808	0.520	0.801 vs. 0.803	0.964

Note: AUC = the area under the receiver operating characteristic curve, US = ultrasound, Rad-score = radiomics score
