Sample size An initial sample size calculation used the estimate of the within-arm SD of cigarettes per day from a pilot study (5.1 (95% CI [3.7, 8.2]: Additional File 1), which indicated that a sample size of 206 participants would give 80% power at the 5% significance level and a two-sided test to detect a difference of two cigarettes per day
Compared with non-smokers, tobacco-only smokers (but not cannabis-only smokers) experienced more frequent respiratory symptoms (odds ratio [OR] 1.50, 95% CI 1.052.14) and were more likely to have COPD (OR 2.74, 95% CI 1.664.52)
