Figure S2 Serial measurements of FVC from −15 min to 24 h post-dose measured in sub-set of patients with serial spirometry measurements. Data are least squares means ± SE. Treatment differences: p<0.001 for indacaterol 600 μg vs placebo at each time point, and for indacaterol 300 μg vs placebo apart from at 8 h (p=0.004), 10 h (p=0.003) and 23 h 10 min (p=0.014); p<0.05 for formoterol vs placebo at time points from 5 min to 8 h and at 11 h 45 min post-dose. P<0.05 for indacaterol 300 μg vs formoterol at −15 min and 11 h 45 min, and for indacaterol 600 μg vs formoterol at all time points apart from 5 min and 1 h post-dose. Patient numbers at each time point are shown in supplementary table S3.
