Data are presented as mean±sd, unless otherwise stated. FEV1: post-bronchodilator forced expiratory volume in 1 s; FVC: post-bronchodilator forced vital capacity; TLC: total lung capacity; RV: residual volume; % pred: % predicted. #: n = 450 because TLC and RV were missing in three patients. ¶: prediction equations from Johannessen et al. 12; +: prediction equations from European Community for Steel and Coal 4.
