A case-control study is conducted to investigate the association between long-term exposure to particulate air pollution (PM2.5) and acute myocardial infarction (AMI). Researchers recruit 100 individuals who have recently experienced an AMI (cases) and 200 individuals from the same community who have not had an AMI (controls). The exposure is defined as living in a high-PM2.5 area for at least 10 years, and data is obtained by asking participants about their prior home addresses. Data collection yields the following results: Among the 100 cases, 60 lived in a high-PM2.5 area. Among the 200 controls, 50 lived in a high-PM2.5 area. Based on the data above, what is the correct measure of association category? (select one) What is the measure of association you calculate? (select one)
