Values are means ± SD. *P<0.05; ^†P<0.01 compared with pretreatment. FEV₁: Forced expiratory volume in 1 s; FVC: Forced vital capacity; FEF₅₀: Forced expiratory flow at 50% of forced vital capacity; FEF₇₅: Forced expiratory flow at 75% of forced vital capacity; MMEF: Maximum mid-expiratory flow rate; PEF: Peak expiratory flow; SD: Standard deviation.
