- In the context of a case-control study, a pro of recruiting incident cases rather than prevalent cases is: a. Incidence is easier to assess than prevalence b. Incidence provides a measure of the burden of disease at one “snapshot” in time c. Using incident cases allows researchers to account for case-deaths that would not be evident if only prevalent cases were considered d. None of the abovearrow_forwardWhich among the following purposes below signifies secondary level promotion? a. To decrease the risk or exposure of the individual or community to disease b. None of the above c. To identify individuals in an early stage of a disease process d.

- Describe the difference between a prevalence-based and an incidence-based cost-of-illness study. A. Prevalence-based studies are useful for budgeting purposes and includes the cost of existing cases and new cases B. Incidence-based studies only consider the costs for new cases during the year C. When completing an explanatory model both are appropriate because there is no difference when it comes to costs, outcomes and cost projections D. All of the above E.
