结局指标
主要结局
Change From Baseline in FEV1 Over 4 Hours
时间窗: 0 (=baseline) to 4 hours after treatment with montelukast
FEV1 measurements taken at 0 (=baseline), 10, 20, 30, 45, 60, 120, 180 and 240 minutes contributed to the average change from baseline over 4 hours. The number of minutes between consecutive measurements was used as weighting factor. The time-weighted average change was standardized by dividing by the time associated with the last measurement.
次要结局
- Change From Baseline in FEV1 Over 90 Minutes After Albuterol/Placebo Administration(4 hours (equals time point at which albuterol or albuterol placebo is administered) to 5.5 hours after treatment with montelukast)
