Unit 8 Practice Questions Epidemiology 6000 Question 1 In a study of endometrial cancer and use of exogenous estrogen, we observe an odds ratio of 2.5. However, we suspect that menopausal status may confound this association. For menopausal status to be a confounder, which of the following are required? a. Menopausal status must be associated with both endometrial cancer and exogenous estrogen use (and menopausal status can not be a result of exogenous estrogen use). b. Menopausal status must be evenly distributed between the exposed and the nonexposed. c. Menopausal status must be evenly distributed between the cases and the controls (and menopausal status can not be a result of exogenous estrogen use). d. Menopausal status must be a stronger risk factor for endometrial cancer compared to exogenous estrogen use. Question 2 An investigator decides that socioeconomic status is indeed a confounder of the association between hormone use and the occurrence of cancer in a case-control study. The investigator looks at the following list of options to control for confounding. Which of the following options can she use? Choose ALL that apply.
