Why is it important and crucial for investigators to examine incidence density rather than cumulative incidence of intravenous drug use (IDU) in the studies that followed non-ID users over time? A. Incidence density increases with a greater follow-up period B. Incidence density is a better measure for a uniform follow-up period C. Incidence density is a rate, and, hence, accounts for different follow-up periods D. None of the above

A case-control study is conducted to estimate the association between sedentary lifestyle and stroke. Researchers enroll 100 patients who had a stroke in the past year and 400 patients who have never had a stroke. Researchers conclude that the prevalence of stroke in the past year in the population is 20%. This conclusion is: Correct Incorrect because prevalence cannot be estimated from a case-control study Incorrect because the prevalence is 25%
State for each of the following statements if they are true or false: a. Cumulative incidence ratio, incidence rate ratio and prevalence are always unitless. b. For a given exposure and outcome, if the incidence rate ratio is < 1, then the incidence rate difference is < 0. c. An odds of 2:3 has the same magnitude as a risk of 2/5. d. In a case-control study comparing the association of a specific exposure between cases and controls, the only measure of association that we can directly calculate is the odds ratio. e. Attributable risk is more informative to policymaking than cumulative incidence ratio. Please answer asap and type your answer and do not copy from anywhere please

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. A and B only
One advantage of case-control studies is that the temporal relationship between exposure and outcome cannot always be ascertained. True or False?
