Data are presented as n, median (interquartile range) or mean±sd, unless otherwise stated. ILD: interstitial lung disease; BMI: body mass index; ITGV: intrathoracic gas volume (estimating functional residual capacity); % pred: % predicted; FVC: forced vital capacity; FEV1: forced expiratory volume in 1 s; RV: residual volume; TLC: total lung capacity; PEF: peak expiratory flow. #: n=12.
