Extra Credit Bantu siderosis is a condition characterized by high levels of serum ferritin (iron) in the blood and occurs primarily in Sub-Saharan African populations. It is thought to be caused by consumption of a specific home-made beer popular in this geographic area. To study this association, the following study is proposed. 500 cases are chosen from a local hospital and the researchers match at controls to the cases at a 1:3 ratio. After investigating whether their participants consumed the beverage or not, they found that 400 people who had Bantu siderosis consumed the drink. Also, 400 people who did not have Bantu siderosis did not consume the drink. Use this information to answer the following questions. 1) Fill in the blanks of the 2x2 contingency table that the researchers would have produced. Bantu siderosis positive Bantu siderosis negative Drank the homemade beer Did not drink the homemade beer Total 2) What study design do you believe is being used? 3) What measure of association is best for this study design? 4) Calculate that measure of association.
