For consumption, we used the midpoint
of the reported
number of cigarettes per day — for example, three cigarettes per day if the category was one to five cigarettes per day — which we then adjusted for carboxyhaemoglobin and cotinine because this allows for lower inhalation with increasing cigarette consumption as previously established.14 For

model contained the logarithm
of the relative risk (dependent variable) and consumption (independent variable) using only the midpoint
of the cigarettes per day categories.
