Dement et al. (1983) used a case-control design to study the relationship between lung cancer and cumulative asbestos exposure in an asbestos textile plant. Refer to the following table to answer the following questions. Exposure distribution of cases and controls: 1,000 fibers/cc X days Table 6-12 Asbestos exposure <1 1-9 10-39 40-99 100 Cases 15 10 11 12 Controls 49 43 28 16 14 Fill in Odds Ratio a) For cases, what are the odds of a cumulative exposure to 2100,000 fibers/cc X days of asbestos? (2 pts). b) Taking the lowest exposure group (i.e. those exposed to <1cc X days of asbestos) as your referent, fill in the odds ratios in Table 6-12. (15pts). c) Interpret each of the 5 odds ratios calculated above. Please provide once sentence each. (10pts)
