Case-control studies are among the best observational designs to study diseases of Question 1 options: high prevalence high validity low case fatality low prevalence A large medical center’s oncology program reported an increased number of cases of pancreatic cancer during a certain month. The hospital’s epidemiologist decided to research the problem. Tumor registry records were searched to identify all cases of pancreatic cancer during a five-year period; cancer patients were matched with patients treated for other diseases during the same five-year period. All subjects in the study were questioned about lifestyle factors including alcohol, tea, and coffee consumption. The resulting data are as follows: Cancer Patients Other Patients Men Women Men Women LIFESTYLE VARIABLE Alcohol 185 120 270 260 Tea Drinking 140 110 230 225 Coffee Drinking 190 140 270 240 Note:   Total number of male cancer patients = 200. Total number of female cancer patients = 150. Total number of male patients (other diseases) = 300. Total number of female patients (other diseases) = 300. Use this data to answer the next 5 questions. type of study is this? Question 2 options: Case-control Cohort Case-series Descriptive Does this study have an exposure status variable? Question 3 options: Yes, lifestyle Yes, disease type Yes, gender of patient Yes, gender of patient and disease type Which number best approximates risk associated with Alcohol Drinking among Men: Question 4 options: 2.11 0.92 0.71 1.37 Which number best approximates risk associated with Coffee Drinking among Men? Question 5 options: 2.11 0.94 1.02 3.50 Based on your calculations above, which factor has the strongest association with cancer for men? Question 6 options: the factors show no variation in the association not enough information to determine Coffee drinking Alcohol consumption
