Table 2 Prognostic factors associated with the clinical cure rate 7–10 days after the end of treatment using a stepwise logistic model (ITT population).

Parameter	Odds ratio	Probability	95% Confidence interval
			Lower limit	Upper limit
Treatment (0 = comparator; 1 = moxifloxacin)	1.485	0.015	1.079	2.044
Cardiopulmonary disease (0 = no; 1 = yes)	0.585	0.016	0.378	0.903
FEV1 (%) at enrolment (0 = ⩾50; 1 = <50)	0.482	<0.001	0.349	0.666
Number of AECBs in previous year (0 = 2–3; 1 = ⩾4)	0.684	0.032	0.483	0.967

There was no interaction between treatment and any of the individual factors (cardiopulmonary, p = 0.241; FEV₁, p = 0.452; number of AECBs in previous year, p = 0.547).
