Diagnostic performance of DOSM, DM, DOM, and GM for MVI classification.

Model type	AUC (%, 95% CI)	Accuracy (%)	Sensitivity (%)	Specificity (%)
DOSM	95.01 (0.835–0.993)	92.86	85.71	100
DOM	91.84 (0.792–0.980)	88.1	80.95	95.24
DM	90.93 (0.780–0.976)	85.71	80.95	90.48
GM	85.94 (0.717–0.947)	83.33	80.95	85.71

AUC, area under the receiver operating characteristic curve; DOSM, MVI prediction model based on DEA feature map, OND feature map and SDSD feature map of ORF signals; DM, MVI prediction model based on DEA feature map; DOM, MVI prediction model based on DEA feature map and OND feature map; GM, MVI prediction model based on gray-scale ultrasound image.
