  1. *Values are means and corresponding standard deviations (SD) unless stated otherwise. **FEV1 predicted: Forced expiratory volume in 1 second, post-bronchodilator, predicted according to age and height. ***FER: forced expiratory ratio (FEV1 / FVC x 100%), FVC: forced vital capacity. ****Mild = FEV1 > 80%, Moderate = 50% ≤ FEV1 < 80%, Severe = 30% ≤ FEV1 <50%, Very severe = FEV1 < 30%
