CT-TLV: total lung capacity calculated on inspiratory CT; pred TLC: predicted total lung capacity; LAV_{−950}%: low attenuation volume <−950 Hounsfield units (HU) at end inspiration; LAV_{−856}%: low attenuation volume <−856 HU at end expiration; fSAD: functional small airway disease. All values are expressed as median (interquartile range).
