In a case-control study examining the relationship between hypertension and myocardial infarction, there were 20,000 participants. Half of the study subjects had hypertension. Among those with hypertension, 180 had a myocardial infarction. Among those who did not have hypertension, only 30 had a myocardial infarction. What is the odds ratio?
Those with hypertension have 6 times the risk of developing a myocardial infarction compared to those without hypertension.
Those with hypertension have 6 times the odds of developing a myocardial infarction compared to those without hypertension.

A five-year study was conducted to examine the relationship between dark chocolate consumption and heart disease. Participants were assessed each year. Those who ate dark chocolate contributed a total of 15,000 person-years, while those who did not eat dark chocolate contributed 20,000 person-years. 300 of those who ate dark chocolate developed heart disease, while 700 of those who did not eat dark chocolate developed heart disease. What is the rate ratio?
Those who ate dark chocolate had 0.43 times the risk of developing heart disease compared to those who did not.
Those who ate dark chocolate had 0.32 times the risk of developing heart disease compared to those who did not.
Those who ate dark chocolate had 1.75 times the risk of developing heart disease compared to those who did not.
Those who ate dark chocolate had 3.11 times the risk of developing heart disease compared to those who did not.

A multicenter double-blind randomized study was carried out to compare the effect of drug X with that of a placebo in patients surviving acute myocardial infarction (AMI). Treatment with the drug started 7 days after infarction in 1,884 patients, 52% of all persons who were evaluated for entry into the study. 945 participants were randomized to treatment with drug X while 939 were assigned to the placebo group. Patients were then followed for 12 months for reinfarction. There were 152...

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...
