In a clinical trial of 2198 subjects treated with a certain drug, 26 reported headaches. In a control group of 1661 subjects given a placebo, 22 reported headaches. Denoting the proportion of headaches in the treatment group by pr and denoting the proportion of headaches in the control (placebo) group by p the relative risk is p/pc. 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 Pt/ (1-Pt) The relative risk and odds ratios are commonly used in medicine and epidemiological studies. Find the relative risk and odds ratio for the Pc/(1-Pc) headache data. What do the results suggest about the risk of a headache from the drug treatment?

![In a clinical trial of 2198 subjects treated with a certain drug, 26 reported headaches. In a control group of 1661 subjects given a placebo, 22 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 Pc
the relative risk is p/pc. 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
. The relative risk and 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?
