Data are presented as mean±sem and median (interquartile range), unless otherwise stated. FEV1: forced expiratory volume in one second; % pred: per cent predicted; FVC: forced vital capacity; W/H: weight for height; Ig: immunoglobulin. #: differences in disease severity markers were more pronounced in the paediatric age group; ¶: using unpaired t-test; +: using Mann–Whitney U-test.
