Table 3.

Number of patients (and % of total) with respiratory events suggestive of administration-related bronchoconstriction during the 30 minutes immediately after inhalation of study treatment on at least one test day. Patients are grouped according to the worst category of event experienced. See text for detailed definition of categories
