Performance of model in diagnosing malignant nodules on test set and its subsets.

	AUC	Accuracy	Sensitivity	Specificity	Precision
Test set	0.924 (0.006)	0.851 (0.018)	0.881 (0.027)	0.839 (0.031)	0.673 (0.038)
HT subset	0.924 (0.010)	0.852 (0.026)	0.881 (0.035)	0.846 (0.036)	0.540 (0.053)
Normal subset	0.906 (0.010)	0.843 (0.011)	0.871 (0.033)	0.822 (0.029)	0.784 (0.024)
P-Value		0.587	0.938	0.178	<0.01

P-Value is that of diagnostic performance on HT subset versus normal subset; AUC, Areas under the ROC curve. All metrics were the average of 10-fold, presented as Mean (SD).
