Change in Pulmonary Function as Measured by FEV1 and FVC
Tidsramme: From baseline to Day 14
|
FEV1 (forced expiratory volume in 1 second) and FVC (forced vital capacity) were recorded at Day 0 (baseline) and Day 14. Change in FEV1 and FVC from baseline to Day 14 was reported as a percentage of values predicted for age, height, and race.
