Comparison of airway dimensions between cystic fibrosis (CF) patients and controls

Significant difference between disease status (Control/CF)	AinA-ratio	AoutA-ratio	AWTA-ratio	AWT-ratio
Inspiration	0.156	<0.001*	<0.001*	0.215
Expiration	0.996	0.003*	<0.001*	0.036*

P-values of mixed-effect model analysis of differences between airway dimensions between CF and control patients. A_outA and A_WTA -ratios were higher in CF patients than controls in both inspiratory and expiratory scans. A_inA-ratios was not significant and the A_WT-ratio only in the expiratory subgroup
