  1. FVC forced vital capacity; FEV1 forced expiratory volume in one second; FEV1/FVC: the ratio of forced expiratory volume in one second to forced vital capacity; FEF25 Forced expiratory flow 25% of FVC; FEF50 Forced expiratory flow 50% of FVC; MMEF maximal mid-expiratory flow; % pred: % predicted. A P value of less than 0.05 was statistically significant.
