FEV1: forced expiratory volume in 1 s; FVC: forced vital capacity; FEF25–75%: forced expiratory flow at 25–75% of FVC; DLCOcSB: single-breath diffusing capacity for carbon monoxide corrected for haemoglobin; VA: alveolar volume; TLC: total lung capacity. #: values in parentheses are the percentage changes compared with the day of admittance.
