Part 4: Complete the problem below about confounding. Show all your work. Answer the discussion questions using complete sentences. To determine whether baldness causes coronary heart disease (CHD) in men, a hypothetical cohort study was carried out. The epidemiologist in charge of the study recruited 10,000 bald men and 10,000 men with hair into the study and followed all of them for 10 years to determine whether they developed CHD. Results are shown below. Bald CHD 1,550 No CHD Total 18,450 20,000 Hairy Total 380 1,930 19,620 20,000 38,070 40,000 1. Using the table above, what is the risk ratio of CHD associated with baldness? Include an interpretation of the Risk Ratio. 2. Does the risk ratio calculated suggest that baldness may be a cause of CHD? If so, what alternate explanation can you provide for the association between baldness and CHD?
