Percentage of (a) controlled (ACQ < 4) and (b) fully controlled patients (ACQ < 1) in the worst and best scenarios. Best scenario: Patients with missing ACQ total scores were considered "controlled" if ACQ scores were <4 in any one assessment, and patients were not dropped out owing to efficacy. Worst scenario: Patients with missing ACQ total scores at 6 or 12 months follow-up visits were considered "not controlled". *Responders were patients who achieved asthma control (ACQ < 4) at both 6 and 12 months.
