Question 2

Grodstein and colleagues (2000) reported on the relationship between duration, dose, and type of postmenopausal hormone therapy and the risk of coronary heart disease in women. Subjects in the study were selected from the Nurses’ Health Study originally completed in 1976; the study included 120,000 married female registered nurses, aged 30–55. The original survey provided information on the subjects’ age, parental history of myocardial infarction, smoking status, height, weight, use of oral contraceptives or postmenopausal hormones, and history of myo cardial infarction or angina pectoris, diabetes, hypertension, or high serum cholesterol levels. Follow-up surveys were every 2 years thereafter.
