Data are presented as n, mean±sd or median (interquartile range), unless otherwise stated. FeNO: exhaled nitric oxide fraction; FEV1: forced expiratory volume in 1 s; FVC: forced vital capacity; PEF: peak expiratory flow; MVV: maximal voluntary ventilation. #: data analysed using Mann–Whitney U-tests.
