  • Data are presented as mean±sd, unless otherwise stated. FVC: forced vital capacity; % pred: % predicted; FEV1: forced expiratory volume in 1 s; TLC: total lung capacity; DL,CO: diffusing capacity for carbon monoxide. #: there were seven measurements in the fibrotic group and 11 in the non-fibrotic group.
