Calculation from absolute risk reduction Flashcard Deck - 10 Cards
Flashcard 1: What is the equation for attributable risk percent in the exposed (ARPexposed)?_____
Answer: ARPexposed = 100 x [(RR-1)/RR]
Flashcard 2: _____ studies are useful for calculating relative risk (RR)
Answer: Cohort
Flashcard 3: _____ studies are observational studies that compare a group of people with disease to a group without disease
Answer: Case-control
Flashcard 4: _____ risk reduction is the proportion of risk reduction attributable to an intervention compared to a control
Answer: Relative
Flashcard 5: The number needed to harm (NNH) is equal to _____
Answer: 1/AR
Flashcard 6: The statistical power of a study is calculated by _____
Answer: 1- beta
Flashcard 7: Cumulative incidence = (# of new cases over a specific period) / (number of people at risk at the _____ of the period)
Answer: beginning
Flashcard 8: attributable risk/absolute risk reduction (epidemiology)
Answer: the difference in risk between exposed and unexposed groups (attributable risk used for risk-enhancing factors ARR used for risk-reducing interventions)
Flashcard 9: number needed to harm (NNH) (epidemiology)
Answer: The number of patients who must be exposed in order to cause 1 event.
Extra: NNH = 1/attributable risk
Flashcard 10: number needed to treat (NNT) (epidemiology)
Answer: The number of patients who must be treated in order to prevent 1 event.
Extra: NNT = 1/absolute risk reduction
