Table 3.

Number of patients with at least one hospitalization by discontinuation of anticholinergics

	Placebo (n = 5868) n (%)	Tiotropium (n = 6295) n (%)	Odds ratio (95% confidence interval)	P value
Discontinued	315 (11.3)	320 (10.4)	0.92 (0.78–1.09)	0.3173
Not discontinued	255 (8.3)	215 (6.7)	0.79 (0.66–0.96)	0.0160
Difference				0.2473

Notes: Results are based on a logistic regression model with terms for treatment, subgroup, trial and treatment *subgroup interaction. The denominator for the percentages is the number of patients in each combination of subgroup and treatment: discontinued: n (placebo) = 2783, n (tiotropium) = 3063; not discontinued: n (placebo) = 3085, n (tiotropium) = 3232.
