Model parameters from the limited multivariate logistic regression analysis. The two models predicts the classification in the first group (1)

Multivariate logistic regression model	Estimate	SE	z value	Pr (>)
Model 1: Patients with CT infiltrates (1) vs. patients without CT infiltrate
Intercept	- 3.606	1.576	2.288	0.022
KL-6	0.0127	0.005	2.317	0.021
CRP	0.269	0.147	1.824	0.068
Model 2: Patients with CT infiltrates who developed symptoms (1) vs. patients without CT infiltrate nor clinical symptom
Intercept	- 0.636	0.412	- 1.543	0.123
Presence of consolidation	1.398	0.616	2.270	0.023

Abbreviations: SE, standard error; CRP, C-reactive protein; CT, computed tomography
