(a) Pre-dose FEV1 (raw values in litres) at time −10 min and post-dose FEV1 at 30, 60, 90, 120, 150 and 180 min, by treatment group at baseline and last study visit; (b) FEV1 AUC0–3h; (c) FVC AUC0–3h; (d) trough FEV1; and (e) trough FVC by treatment group during the course of the study. AUC0–3h, area under the curve between 0 and 3 h; CI, confidence interval; FEV1, forced expiratory volume in 1s; FVC, forced vital capacity; LS, least squares.
