B) Use specific, descriptive terms for risk.
C) Use a consistent denominator.
D) Use visual aids.

Question 5

Which is the correct formula for measuring population absolute risk?

A) Multiply the absolute risk for the incidence of an adverse event by the prevalence of the use of the medication in the population.
B) Divide the absolute risk by the prevalence of use in a small subset of the population.
C) Multiply the absolute risk for the incidence of a statistically significant adverse event by the likelihood of the medication being taken as directed.
D) Divide the possibility of an adverse event occurring by the number of persons likely to be taking the medication.
