- 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:
- In case-control studies, the odds ratio is used as an estimate of the relative risk. In order for this approximation to be reasonable, some conditions must be met. Which of the following conditions is not necessary in order to use the odds ratio to estimate the relative risk?
- Examples of descriptive epidemiologic studies do not usually include:
- True or False? A case-control study is purely a descriptive (as opposed to analytic) study design
- Examples of exposure data in ecologic studies include:
- True or False? An ecologic study is one that examines a group as a unit of analysis.
- True or False? An ecologic comparison study is sometimes called a cross- sectional ecologic study.
