Characteristics of LCCM features in the training cohort

Predictors	Coefficient (95% CI)	P value
Years since quit smoking	−0.178 (−0.349 to −0.007)	0.041
Number of vessels	0.238 (0.074 to 0.510)	0.009
Number of nodules	−0.203 (−0.325 to −0.081)	0.001
Model intercept	1.053

The numbers in lung cancer and benign nodules correspond to the average values and SD of the corresponding features in the two classes. Coefficients were estimated using multiple logistic regression.
