Results are presented as n (%) or median (IQR). % predicted of FEV1 and FVC was calculated on ECSC equations before 2012 and on GLI equations from 2012. NA, not applicable; BMI, body mass index; FEV1, forced expiratory volume in 1 second; FVC, forced vital capacity; FEV1/FVC, Tiffeneau index; DLCO, diffusion capacity of the lung for carbon monoxide. P-value >0.05 was considered non-significant (ns) (Wilcoxon-Mann-Withney test).
