Design outcomes
Secondary
| Measure | Time frame |
|---|---|
| Comparison of the change in peak flow values between the two groups, (Arg/Arg vs. Gly/Gly) in the period when receiving salmeterol plus ICS Comparison of the change in peak flow values between the two groups, (Arg/Arg vs. Gly/Gly) in the period when receiving montelukast plus ICS The other outcome measurements include asthma control test, peripheral eosinophil count, and pulmonary function parameters | — |
Primary
| Measure | Time frame |
|---|---|
| Comparison of the change in peak flow values over 4 months between the two groups who will be receiving salmeterol plus Inhaled corticosteroid (ICS) and who will be receiving montelukast plus ICS, based on stratification of beta2-adrenergic receptor gene pormorphism (Arg/Arg vs Gly/Gly) | — |
