Change from baseline in FEV ₁ over time. Data are presented as least squares means with 95% confidence intervals: a) p < 0.0001 versus placebo for salbutamol and all doses of abediterol at all time points; b) p < 0.0001 for all doses of abediterol 0–24 h post-dose and abediterol 1.25 and 2.5 μg 36 h post-dose versus placebo, p = 0.002 and p = 0.01 for abediterol 0.313 and 0.625 μg, respectively, at 36 h post-dose versus placebo. FEV₁, forced expiratory volume in 1 s.
