Results are expressed in Z score or in % of predicted values; mean (±SD).
P values are calculated with for Z scores and express the difference between the analysed group and the reference values.
DLCO, diffusing capacity for carbon monoxide; FEF25-75, forced expiratory flow from 25% to 75% of expiration; FEV1, forced expiratory volume in 1 s; FVC, forced vital capacity; TLC, total lung capacity; VC, vital capacity.
