Fig 1 CONSORT diagram. Of the patients screened, the main reasons for noninclusion were as follows: adverse event (n = 3), consent withdrawn (n = 11), violation of inclusion or exclusion criteria (n = 243), lost to follow-up (n = 3), and other (n = 15). Of those randomized, 1 patient randomized to 5 μg of tiotropium administered through the Respimat device was not treated. AE, Adverse event; QD, once daily.

Fig 2 Peak FEV1(0-3h) response at week 24: full analysis set. Results are adjusted for treatment, country, week, baseline, treatment-by-week interaction, and baseline-by-week interaction. Error bars are ± SEs. Common baseline mean FEV1 ± SD is 2747 ± 662 mL. **P < .01 versus placebo Respimat and ***P < .001 versus placebo Respimat. Peak FEV1(0-3h), Peak FEV1 within 3 hours after dosing; QD, once daily.

Results are adjusted for treatment, country, week, baseline, treatment-by-week interaction, and baseline-by-week interaction. Common baseline mean ± SD is 2.48 ± 0.97 L/s. *P < .05 versus placebo Respimat, **P < .01 versus placebo Respimat, and ***P < .001 versus placebo Respimat. QD, Once daily.

Fig 5 Adjusted mean predose morning (A) and evening (B) PEF responses at weeks 24 and 48: full analysis set. Results are adjusted for treatment, country, week, baseline, treatment-by-week interaction, and baseline-by-week interaction. Common baseline mean predose morning PEF ± SD is 339.7 ± 91.5 L/min; common baseline predose evening PEF ± SD is 359.9 ± 91.1 L/min. Adjusted mean predose morning and evening PEF responses versus placebo were as follows: 5 μg of tiotropium, P = .02 and P = .01, respectively, at week 24 and P = .005 and P = .008, respectively, at week 48; 2.5 μg of tiotropium, P = .17 and P = .08, respectively, at week 24 and P = .0504 and P = .03, respectively, at week 48. *P < .05 versus placebo Respimat and **P < .01 versus placebo Respimat.

Fig E1 Study design. Patients randomized to placebo received background ICS maintenance treatment with or without an LTRA as active therapy only. In-clinic spirometric evaluations were conducted at baseline (visit 2; randomization) and subsequently at visits 4, 6, and 8 in the evening. QD, Once daily.
