In a cohort study, middle-aged men and women with moderate alcohol intake (exposed group) and no alcohol intake (unexposed group) were followed in time to study the outcome of first myocardial infarction (MI). Among m there were 250 new cases of MI after 20,000 person years of follow-up in the exposed group, and 60 cases of new MI after 10,000 person-years of follow-up in the unexposed group. Among women, there were 30 new cases of MI in the exposed group after 10,000 person-years follow-up, and 40 new cases of MI in the unexposed after 20,000 person-years of follow-up.
