Mean (SE) trough, peak and average (over 6 hours) response in FEV1 and FVC after tiotropium and ipratropium

  • The baseline means are adjusted for centre effects. All other means are adjusted for centre effects and baseline FEV1 or FVC. The common baseline mean FEV1 is 1.19 l (tiotropium 1.21 l, ipratropium 1.15 l, p>0.05); the common baseline mean FVC is 2.69 l (tiotropium 2.75 l, ipratropium 2.57 l, p>0.05).
