Question 15
3 / 3 pts
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:

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.
Which number best approximates risk associated with alcohol Drinking in Men?
2.11
0.92
0.71
0.62
1.37
Question 16
3 / 3 pts
Examples of descriptive epidemiologic studies do not usually include:
Cohort studies
Counts
Case series
Cross-sectional studies
Question 17
3 / 3 pts
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?
With respect to exposure, controls are representative of the population to which you want to generalize
your results.
The event (disease) under study is rare in the population.
The exposure in question is rare in the population.
Cases are representative of all cases.
Question 18
3 / 3 pts

True
False
Question 19
3 / 3 pts
Case-control studies are among the best observational designs to study diseases of:
high prevalence
high validity

low prevalence
Question 20
3 / 3 pts
True or False? An ecologic study is one that examines a group as a unit of analysis.
True
False
Question 21
3 / 3 pts
True or False? Controls are needed in a case-control study to evaluate whether the frequency of a factor
or past exposure among the cases is different from that among comparable persons who do not have the

True
False
Question 22

and disease.
True
