SECONDARY outcome

Timeframe: 5 days

Population: Participants who had complete data available for analysis

Severity of asthma symptoms as reported by the Patient Self Assessment Score. Patients assessed severity of asthma symptoms in 4 categories (wheezing, coughing, activity and sleep) once per day during the 5 days between study enrollment and follow-up. Score range is 0 - 12 with 0 being mildest symptoms and 12 being most severe symptoms. Reported as change in score between enrollment (day 1) and follow-up (day 5).
