'Well-controlled Asthma Week' - a Derived Binary Variable (Yes/No)
Query!
Assessment method [1]
0
0
A well-controlled asthma week is defined as the fulfilment of both conditions A) and B) below: A) Two or more of the following criteria are fulfilled: - No more than 2 days with a daily asthma symptom score >1 - No more than 2 days of 'as needed' medication use, up to a maximum of 4 occasions per week (multiple occasions per day should be regarded as separate occasions) - Morning PEF =80% of Predicted Normal every day B) Both of the following criteria are fulfilled: - No nighttime awakenings due to asthma - No additional inhaled and/or systemic glucocorticosteroid treatment due to asthma. The binary variable well-controlled asthma week was derived for each patient and study week. In addition, for each week, the percent of patients with well-controlled asthma week was derived. It is required that the eDiary had to be completed on at least 5 days in a week to be a well-controlled asthma week.

Asthma symptom score (eDiary) change from baseline during the randomised treatment period. Symptom score is entered morning and evening by the patient on a 4-point scale from 0 to 3 with higher values indicating more severe symptoms. Asthma symptom score is then the sum of the day and night scores, which implies a range of scores from 0 - 6, with higher values indicating more severe symptoms. Baseline is defined as the mean of all non-missing measurements during the last 10 days of the run-in period.
