  1. Analyses were performed on the ITT population. For both placebo and indacaterol, N = 68
  2. LS mean differences and p-values obtained from an ANCOVA model for crossover designs with change from baseline in FEV1 variable as response, sequence, treatment group and period as fixed effect factors, patient within sequence as a random effect and the corresponding baseline value at each period as a covariate
  3. ANCOVA, analysis of covariance; AUC 0-12 area under the curve over the 12 h period immediately after morning IMP administration, AUC 12-24 area under the curve over the 12 h nighttime period after morning IMP administration, AUC 0-24 area under the curve over the 24 h period immediately after morning IMP administration, FEV 1 forced expiratory volume in 1 s, IMP investigational medicinal product, ITT intent-to-treat, LS least squares, N ITT population size of treatment group
