Part II: Hookah Smoking and Lung Cancer ( 5 points )
You are planning to study the relationship of small cell lung cancer and exposure to Hooka h smoking by using a hospital - based case – control study. Hospitalized individuals with small cell lung cancer will be compared with hospitalized patients without small cell lung cancer (controls). Your hospital is located in a low - income area of New Haven, CT, is famous nationwide for its expertise in small cell lung cancer; individuals with small cell lung cancer (cases) from all over the United States come to your hospital to get the best care in the world. However, your hospital is not as well known for a ny other medical conditions as it is for small cell lung cancer. Therefore, cases would come from all over the US, and controls will be mostly from New Haven low - income individuals. You are predicting that an overestimation of the relationship between smal l cell lung cancer and Hookah smoking is possible.
