To the Editor: Prospective studies have shown
that moderate alcohol drinkers have lower all-cause mortality than nondrinkers.1 Subjects in the nondrinkers category generally
comprise both never drinkers and ex-drinkers. Although ex-drinkers might have
quit drinking due to ill health and have higher mortality than never drinkers,
many studies fail to consider them separately.1
We examined the effect of combining and separating the 2 groups on the relationship
between moderate drinking and total mortality.
