In a clinical trial of 2134 subjects treated with a certain drug, 27 reported headaches. In a control group of 1666 subjects given a placebo, 26 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 pe, the relative risk is p/pe. 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 Pt/ (1-Pt) treatment group to the odds in favor of a headache for the control (placebo) group, found by evaluating The relative risk and odds ratios are commonly used Pc/ (1-Pc) 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 the odds ratio is greater than 1.0. O B. The drug has no risk because the relative risk and odds ratio are almost equal. O C. The drug appears to pose a risk of headaches because p, is greater than Pc- O D. The drug does not appear to pose a risk of headaches because p, is slightly less than p..
