Figure 2 Adjusted mean peak FEV1(0-3h) response over the 12-week study period. *P < .05; **P < .001. Response defined as a difference from the baseline value at randomization. Error bars are ± standard error. Baseline mean (standard deviation) FEV1, mL, at visit 2: 2420 (711). Adjusted for treatment, center, visit, baseline, treatment-by-visit interaction, and baseline-by-visit interaction. FEV1, forced expiratory volume in 1 second; peak FEV1(0-3h), peak forced expiratory volume in 1 second within 3 hours of dosing.

Figure 3 Adjusted mean weekly morning PEF (A) and adjusted mean weekly evening PEF (pre-bronchodilator) (B). P < .05 vs placebo for both tiotropium doses at all time points. Response defined as a difference from the baseline value at randomization. Error bars are ± standard error. Baseline mean (standard deviation) PEF, L/min, at visit 2: morning, 355.8 (114.5); evening, 369.8 (115.0). PEF, peak expiratory flow.
