a To be included within this category, participants had to be both self-reported non-smokers and have a saliva cotinine level lower than 12ng/ml.
b Geometric means have been presented for non-smokers as their cotinine data have a very skewed and exponential distribution. A geometric mean is an average calculated by multiplying the values of the cases in the sample and taking the nth root, where n is the number of cases. As 95% confidence intervals for the geometric means are more complicated to calculate than for arithmetic means, these have been presented around the estimates rather than standard errors
c Non-smokers with a detectable level of cotinine in their saliva (> 0.1ng/ml).
