However, the lower dose of tiotropium 2.5 μ g did show nominally significant improvement in peak FEV 1(0–3h) response versus placebo add-on at Week 12 (111 mL, 95% CI 2–220, P=0.046).

Trial 2 of PrimoTinA-asthma showed a significant improvement in patients' seven-question Asthma Control Questionnaire (ACQ-7) score (–0.2, P=0.003), even though the effect in trial 1 did not reach statistical significance (–0.13, P=0.06).
