Adjusted for age, sex, height, weight. significant findings (P<0.05) are with *. FVC, forced vital capacity; FEV1, forced expiratory volume in the first second; PEF, peak expiratory flow; FEF25–75%, orced expiratory flow between 25% and 75% of expired volume; MVV, maximum voluntary ventilation; VC, vital capacity; FEF25%, forced expiratory flow at 25% of expired volume; FEF75%,forced expiratory flow at 75% of expired volume.
