FEV1 indicates forced expiratory volume in 1 second; % pred, percentage of predicted value; 95% CI, 95% confidence interval; NS, not significant; FVC, forced vital capacity; TLC, total lung capacity; RV, residual volume; TLCO, lung diffusion capacity for CO.
Mean values and SD in all patients, compared with reference population, mean values and SD per disease group, and comparison between disease groups.
