Calculate the concordance rate for the following data:

622 649 c. Calculate the appropriate measure of association for the study. (4 points) d. Interpret the results. (2 points) 2. In another study, the smoking habits of 34,445 male physicians were obtained by mailed questionnaires. Deaths among these physicians over the subsequent years were identified though contact with the office of the Registrar General. The death rates from lung cancer of these physicians classified by smoking habits were : Standardized Death Rates per 1000 Persons Aged 35 or More per Year Nonsmokers 0.07 Cigarette Smokers 0.96 a. Name the type of study. (2 points) b. Calculate the Relative Risk for smokers as compared to nonsmokers. (6 points) c. Interpret the results (2 points) Annual Death Rates per 100,000 Persons Exposure Category Lung Cancer Heavy Smokers Nonsmokers Coronary Heart Disease 166 7 599 422 a. Calculate the relative risk from Lung Cancer Mortality for Heavy Smokers compared to non smokers. ( 4 points) b. Calculate the attributable risk of Lung Cancer from smoking. (4 points) c. Interpret the results. (2 points) d. Calculate the percent attributable risk of Coronary Heart Disease due to smoking (4 points) e. Interpret the results. (2 points) 3. Convert the following incidence rates to attributable risk using the additive model: (5 points) Incidence Rates Relative Risks Factor A Factor A _ Factor B – + 3.0 _ + 9.0 _____________________________________ __________________________________ + 15.0 21.00 4. Calculate the concordance rate for the following data: (5 points) Twin 1 Has Leukemia Twin 2 Does Not Have Leukemia Has Leukemia 14 1 Does Not Have
