Notes: aNumber of pack-years smoked = (number of cigarettes each day/20) × number of years smoked. bSeverity of COPD was based on the non-missing post-salbutamol assessment at screening. cThese patients were characterized as having mild COPD due to the application of an Asian correction factor to baseline lung function assessments at the time of analysis. dReversible is defined as improvement in FEV1 post-salbutamol administration compared to pre-salbutamol of ≥12% and ≥200 mL. eDefined as using ICS on the day of the first dose of study medication. fCAT total score is the sum of eight CAT item scores (range: 0–40). gRescue medication use was analyzed in the China rescue medication user population, defined as all patients in the China ITT population with mean baseline rescue salbutamol use of ≥1 puff/day.
