Scenario 1: A group of researchers conducted a case-control study to examine the relationship between pancreatic cancer and prolonged exposure to asbestos among adult workers in the shipping industry aged 45-64 years of age in a small coastal town. Controls were selected from people in the same town employed in occupations not related to the shipping industry. The researchers enrolled 200 participants. Among the participants, 100 had pancreatic cancer and 48 reported prolonged exposure to asbestos. Among those without prolonged exposure to asbestos, 70 had pancreatic cancer. HINT: To respond to the items related to this scenario, construct a contingency table as demonstrated in the course text. Use the information provided to calculate the missing information for the table. You have all of the information you need to do this. 2. Calculate the odds ratio comparing cases of pancreatic cancer among those with prolonged exposure to asbestos to cases of pancreatic cancer among those without prolonged exposure to asbestos.
3. In your own words, interpret the odds ratio you calculated. In your interpretation, indicate the percentage increase or decrease.
