^a‘Non-drinkers’ (no alcohol consumption), ‘light/moderate drinkers’ (consuming between 1 and 6 alcoholic drinks on a typical day) and ‘heavy drinkers’ (consumed 7 or more alcoholic drinks on a typical day)

^b p values for the global F statistic of the three levels alcohol consumption are derived from a Wald test; ‘non-drinkers’ was the baseline category for alcohol consumption
