Combined analysis of MMP-7 and free circulating DNA, considered as continuous variables in a multiple logistic regression model adjusted for age, gender and smoking habits of NSCLC patients compared to the other lung diseases (except IPF) and healthy donors.

Variable	Coefficient (Standard Error)	Wald Test	OR (95% CI)	p
Constant	−15.48137	−3.05	-	-
ln MMP7	1.04992	1.87	2.86 (0.95–8.60)	0.062
ln DNA	1.344679	4.09	3.84 (2.01–7.30)	<0.0001

LOGIT = −15.48137 + 1.04992 ln MMP-7 + 1.344679 ln DNA.
