  1. BPD-, preterm- and asthma-groups were compared to healthy controls. Data are presented as numbers (%). FEV1, FVC, FEV1/FVC: post bronchodilator measures. *p ≤ 0.05; **p ≤ 0.01; ***p ≤ 0.001. Abbreviations: BPD bronchopulmonary dysplasia, FEV1 forced expiratory volume in 1 s, FVC forced vital capacity, LCI lung clearance index
