Step by step
Solved in 2 steps
- Epidemiology 1. True or False: Prevalence is a measure of association used to estimate the rate of disease occurrence in studies of screening programs. 2. True or False: Incidence is a measure of disease frequency used to estimate the risk or rate of exposure in diagnostic test studies. 3. True or False: A number needed to screen of 20,000 would mean that for every 100,000 people screened, 5 would benefit. 4. True or False: A screening program with a number needed to harm of 1000 would be consistent with a risk of harm of 0.002 in the screening group and 0.001 in those not screened.Epidemiology 1. True or False: Positive predictive value of a screening test depends on its sensitivity and specificity and the prevalence of the disease being tested for in the community. 2. True or False: Negative predictive value of a screening test depends on its sensitivity and specificity and the prevalence of the disease being tested for in the community.Differentiate between the following terms used in medical epidemiology:4.1. Sporadic vs endemic 4.2. Individual matching vs group matching cases and controls 4.3. Dichotomous test vs continuous variables test
