Diagnostic performance of the texture model, texture-volume-number model, texture-volume model, texture-number model, and manual measurement of the cortical diameter for the training and validation cohorts in differentiating between positive and negative LN metastasis groups

Models	AUC in the training cohort	AUC in the validation cohort
Texture model	0.9944	0.7677
Texture-number model	0.9963	0.7403
Texture-volume model	0.9949	0.8129
Texture-volume-number model	0.9832	0.7448
Manual measurement of cortical diameter	0.5765	0.6851

AUC, area under the curve; LN, lymph node.
