|
Percentage of Asthma-control Days (no Asthma Symptoms, no Awakenings, and no As-needed Use)
Time Frame: 52-week treatment period
|
An asthma-control day was defined as a a night and day with no asthma symptoms, no awakenings due to asthma symptoms, and no as-needed medication use.
The mean value from the treatment period was presented here.

|
Asthma Control Questionnaire (ACQ)
Time Frame: 4, 12, 24, 36 and 52 weeks after randomization
|
The ACQ developed by Juniper and colleagues (Juniper et al 1999) was used without the FEV1 and Beta 2-agonist questions.
The Asthma Control Questionnaire has 5 questions that are assessed on a 7-point scale from 0 to 6 where 0 represents good control and 6 represents poor control.
The overall score is the mean of the five responses.
At least 4 out of the 5 questions must have been answered to provide a value.
The mean of the overall score for Weeks 4 to 52 was presented here.
