  • Data are presented as mean±sd, unless otherwise stated. iVaw: distal airway volume; iRaw: airway resistance determined by computational fluid dynamics; FEV1: forced expiratory volume in 1 s; VC: vital capacity; PEF: peak expiratory flow; Raw: airway resistance; sRaw: specific airway resistance; FRC: functional residual capacity; % pred: % predicted; TLC: total lung capacity. Bold indicates significance.
