For randomization, patients fulfilled the following criteria: 1. Forced Expiratory Volume in one second (FEV1) ≥70% predicted while withholding beta (β)-agonist for at least 6 hours 2. Exercise-induced bronchoconstriction (EIB) showing FEV1 ≥15% reduction from baseline while on inhaled corticosteroids demonstrated twice during the run-in period.
