Week 3 Project Part 1 In a hypothetical cohort study conducted by an independent organization studying lung cancer, they found that out of 2,533 people 315 were diagnosed with lung cancer. 296 of the participants diagnosed with lung cancer smoked. Of the participants who did not have lung cancer, 1259 did not smoke. Calculate each of the following indices and provide an interpretation. 1. What is the incidence of lung cancer? 2. What is the risk ratio (RR) of smoking? How would you interpret this index? 3. What is the attributable risk (AR) of smoking? What is the interpretation of the AR? 4. What is the population attributable risk (APt)? What is the interpretation of the population attributable risk? 5. What is the attributable proportion among the exposed (APe)? Part 2 You are a researcher who is interested in the association of heavy drinking and dying at an early age. Describe how you and your team would conduct a study. In your response be sure to address the following: 1. What is the study design and why? 2. Who is your population of interest? 3. Who does your sample consist of? 4. What is the outcome variable of interest? Define what the outcome variable is and how it will be measured. 5. What are the key variables? Define each of the key variables and how they will be measured. 6. What are the confounding variables? 7. What are the sources of potential bias? 8. What is your approach to data collection? 9. What are the limitations?
