The primary end point was the estimated mean change from baseline through week 24 in the percent of predicted forcedexpiratoryvolume in 1 second (FEV1).
主要终点为自基线至24周的预测1秒钟用力呼气容积（FEV1）百分比的估计平均变化。
2
The forcedexpiratoryvolume in one second (FEV1) was measured before and after inhalation.
测定所有患者用药前后第1秒用力呼气量（FEV1）变化。
3
Pulmonary function tests(PFT), including forced vital capacity(FVC), forced the first second of expiratoryvolume (FEV1) and FEV1/FVC.
