No significant differences were found in baseline characteristics between the intervention group (n = 161) and the control group (n = 160), but there was a numerical trend toward more participants with previous vascular events in the control group (p = 0.092).
Smoking cessation within 1 month was associated with lower all-cause mortality (HR 0.52, 95% CI 0.32–0.87), and there was a nonsignificant trend towards a lower incidence of CV events (HR 0.71, 95% CI 0.45–1.12).
Also, as in previous studies, it is difficult to isolate the effect of smoking cessation alone, since smoking cessation was also associated with other characteristics that were of prognostic importance such as age, the type of index event, and (at a borderline significance level) previous vascular events.
