Adjusted mean±se response in peak forced expiratory volume in 1 s within 3 h post-dosing (peak FEV10–3h) at week 24, following once-daily tiotropium Respimat add-on to high-dose inhaled corticosteroids (ICS) plus a long-acting β2-agonist (LABA) in adults with severe symptomatic asthma, in a) NCT00772538 and b) NCT00776984. Adjusted for treatment, centre, visit, baseline, treatment-by-visit interaction and baseline-by-visit interaction. Full analysis set. c) Cumulative number of severe exacerbations, over 48 weeks, following once-daily tiotropium Respimat add-on to high-dose ICS plus a LABA in adults with severe symptomatic asthma. Pooled data (NCT00772538 and NCT00776984). Risk reduction of 21% (hazard ratio 0.79, p=0.03). Full analysis set. *: p<0.05; **: p<0.01; ***: p<0.001.
