*, P< 0.05; **, P<0.01 vs. ON group by ANCOVA; †, P<0.05; Data are presented as mean ± SD unless otherwise specified. ON, oxygen-driven nebulization; UN, ultrasonic nebulization; UNWO, ultrasonic nebulization with warming and oxygen; FVC, forced vital capacity; FEV1, forced expiratory volume in one second; PEF, peak expiratory flow.
