Multivariate analysis using LV and LAA% to predict MLD

	R²	LV		LAA%

		Std B	p	Std B	p
Inspiratory phase	0.721	−0.336	<0.001	−0.723	<0.0001
Expiratory phase	0.760	−0.458	<0.0001	−0.553	<0.0001

Definition of abbreviations: MLD = mean lung density, LV = lung volume, LAA% = low attenuation area percent (<−950HU), Std B = standardized coefficient B
