In a control group of 1742 subjects given a placebo, 24 reported headaches. Denoting the proportion of headaches in the treatment group by p, and denoting the proportion of headaches in the control (placebo) group by po, the relative risk is p /p. The relative risk is a measure of the strength of the effect of the drug treatment. Another such measure is the odds ratio, which is the ratio of the odds in favor of a headache for the treatment group to the odds in favor of a headache for the control (placebo) group, found by evaluating P+ 1 ( 1 - P1 ) The relative risk and Pc / (1- Pc) odds ratios are commonly used in medicine and epidemiological studies Find the relative risk and odds ratio for the headache data. What do the results suggest about the risk of a headache from the drug treatment? Find the relative risk for the headache data. The relative risk = (Round to three decimal places as needed.) Find the odds ratio for the headache data. The odds ratio = (Round to three decimal places as needed.) What do the results suggest about the risk of a headache from the drug treatment? O A. The drug appears to pose a risk of headaches because p, is greater than pc O B. The drug does not appear to pose a risk of headaches because p, is slightly less than Pc. O C. The drug has no risk because the relative risk and odds ratio are almost equal. O D. The drug appears to pose a risk of headaches because the odds ratio is greater than 1.0
