Data are presented as the mean ± standard deviation. Group A, salmeterol/fluticasone treatment group; Group B, budesonide treatment group; Group C, routine treatment group.

P<0.01 compared with the value prior to treatment;

P<0.01 compared with groups B and C;

P<0.01 compared with group C.

IL, interleukin; FEV₁, percentage of forced expiratory volume in one second; FEV_1%pred, predicted FEV₁; FVC, forced vital capacity; PaO₂, partial pressure of oxygen in arterial blood; PaCO₂, partial pressure of carbon dioxide in arterial blood.
