1. Interpret the meaning of one study’s reported odds ratio of 1.6 (95% CI 1.1, 3.4) for the association between high level of fish oil consumption and prostate cancer.

 

2. Interpret the meaning of an odds ratio of 1.00 for the association between consumption of fish oil and prostate cancer.

 

3. True or false: both a prevalence ratio and a prevalence difference are considered measures of occurrence.

 

4. True or false: both a risk ratio and a risk difference are considered measures of disease occurrence.

 

5. True or false: The term “relative risk” is the most precise term to use when discussing measures of association.

 

6. True or false: The term “relative risk” is sometimes used to refer to any of the ratio measures of association.

 

7. Which of the following are ratio measures used in epidemiology? (You must choose all that apply to receive credit for this question; no partial credit will be awarded.)

 

8. True or false: It is best to use a difference measure when trying to understand the cause or etiology of a health outcome or disease.

 

9. True or false: When a ratio measure is less than 1 it means the prevalence, risk or rate in the exposed is greater than in the unexposed group.

 

10. True or false: When a ratio measure is greater than 1 it means the prevalence, risk or rate in the exposed is greater than in the unexposed group.

 

11. Which of the following is true about a ratio measure that equals 1.0?

 

12. Which of the following is true about a ratio measure is greater than 1.0?

14. True or false: A ratio measure of association expresses the prevalence, risk or rate among exposed in excess of that among the unexposed or less-exposed.

 

15. True or false: A difference measure treats the prevalence, risk or rate of the health outcome among the unexposed group as a “background” prevalence, risk or rate.

 

16. Which of the following is true about a difference measure that is less than 0?

 

17. True or false: The null value used when interpreting a difference measure is 0.
