OBJECTIVE: To systematically review recent evidence on the effectiveness of tiotropium versus placebo, ipratropium, and long-acting β2 agonists on outcomes relevant to patients with stable COPD, including health-related quality of life, dyspnea, exacerbations and hospitalizations. METHODS: Our inclusion criteria for trials were: ≥ 12 weeks; compared tiotropium to placebo, ipratropium, or long-acting /3 agonists; patients ≥ 40 y old and with stable COPD. Sixteen trials (16,301 patients) met the inclusion criteria. RESULTS: Tiotropium improved health-related quality of life (measured with St George's Respiratory Questionnaire) compared to placebo (odds ratio [OR] 1.61, 95% CI 1.38-1.88, P
