  • * Unless otherwise indicated, data are mean±SD or n (%).

  • Difference in change from baseline adjusted for the baseline value of the parameter and centre; corresponding 95% CIs and p values are calculated using ANCOVA.

  • Number of days for patients with at least one exacerbation-related hospital admission.

  • COPD, chronic obstructive pulmonary disease.
