A grоup оf reseаrchers cоnducted а cаse-control study to investigate if distances to a chemical factory (C point on the figure below) is associated with lung cancer in a neighborhood. The researchers identified 20 cases (solid dots) from local hospital death certificates, and randomly selected 30 controls (open dots) without lung cancer. In order to examine the effects of distance, they drew three buffers that are 1 mile, 2 miles, 3 miles away from the factory, respectively (dash-line circles). There are 5 cases and 5 controls within the 1 mile buffer, 9 cases and 10 controls in the 1-2 mile buffer, and 6 cases and 15 controls in the 2-3 mile buffer. Using this information, and setting the 1 mile buffer as your non-exposure (reference) distance, calculate the Odds Ratios of developing lung cancer if living 1-2 miles and 2-3 miles away from the factory. Report your answers using exactly 1 decimal place. Figure: Distances of cases and controls to a chemical factory Table 5: Case-control values and associated Odds Ratios.
