A case-control study was conducted in Auckland, New Zealand, to investigate the effects among regular drinkers of alcohol consumption on both nonfatal myocardial infarction and coronary death in the 24 hours after drinking. Data were tabulated separately for men and women (Table E1.8).
(a) Refer to the myocardial infarction data. Calculate separately for men and women the odds ratio associated with drinking.
(b) Compare the two odds ratios in part (a). When the difference is confirmed properly, we have an effect modification.
(c) Refer to coronary deaths. Calculte separately for men and women the odds ratio associated with drinking.
(d) Compare the two odds ratios in part (c). When the difference is confirmed properly, we have an effect modification.
