A study investigated the effects of oral contraceptive (OC) use on heart disease in women 40 to 44 years of age. The results are displayed in the following contingency table Developed Myocardial Infarction | Did Not Develop Myocardial Infarction OC Users: 13 | 4987 Non-OC Users: 7 | 9993 a. Calculate the odds ratio for the sample data. (5 points) b. Construct a 95% confidence interval for the population odds ratio. (15 points) c. Explain the confidence interval to a patient. Include your opinion on whether myocardial infarction should be a concern as a side effect. (10 points)

Step 1
We also know that there are 9993 OC users. We can find the number of non-OC users by subtracting the number of OC users from the total number of cases (13 + 4987): Total cases = 13 + 4987 = 5000 Non-OC users = 5000 - 9993 = -4993 Now we can complete the Show moreā¦

A study was conducted to determine the effect of oral contractive (OC) use on heart disease risk in 40- to 44-year-old women (fictitious data). This study found 130 new cases of myocardial infarction among 7000 non-OC users followed for 2000 person years. In contrast, among 10,000 OC users followed for 2800 person years, 70 developed a first myocardial infarction. Calculate the Risk Ratio. (5 pts) 2.653 0.769 1.476 0.377

Researchers wanted to test the hypothesis of an association between recent contraceptive use (OC) and myocardial infarction (MI). They conducted an observational study of 234 patients who had experienced an MI and 1742 control patients without MI among those who reported recent oral contraceptive use or not. Among those with recent OC use, 29 had experienced an MI and 135 had not experienced an MI. Use a 2 x 2 table to estimate the appropriate measure of association for this study. Include the leading digit before the decimal and round to 3 decimal places. Odds of OC use among those with MI are_________ Odds of OC use among those without MI are_________ The Odds Ratio is_________

In a study examining the relationship between oral contraceptives and bacteriuria, you enroll and follow healthy women who do and do not use oral contraceptives (OC) and follow them over a three-year period and find that 70 of the 500 individuals who use OC acquired bacteriuria, while 150 of 3000 individuals who donāt use OC acquired bacteriuria. a. What kind of observational study design is this? b. What is the incidence among the exposed? c. What is the incidence among the unexposed? d. What is the relative risk? Show your work. e. Interpret the relative risk naming the exposure and outcome (e.g. describe the association between exposure and outcome).
