Performance data for EGFR, ALK, and KRAS mutation classification models using both clinical data and radiomic features.

Mutation	Accuracy	AUC*	Sensitivity	Specificity	Number of lesions
EGFR	77.7%	0.912	73.1%	90.6%	335
ALK	86.7%	0.915	76.1%	88.7%	71
KRAS	96.7%	0.985	89.3%	97.7%	56

^*AUC: area under the receiver operating characteristic curve

Note: Number of lesions indicates the lesions for each positive gene mutation, i.e., EGFR, or ALK, or KRAS. In the classification of each mutation status, the total number of 462 lesions were divided into two classes for each mutation, those positive to the particular mutation versus the rest of the lesions.
