Answer: Cohort

Flashcard 2: _____ risk is defined as the difference in risk between exposed and unexposed groups

Answer: Attributable

Flashcard 3: If relative risk _____ 1, exposure is associated with increased disease occurence

Answer: >

Flashcard 4: What kind of study compares a group with an exposure to another group without an exposure and looks for differences in disease outcomes between the two groups.

Answer: Cohort study

Flashcard 5: Explain how a cohort study works.

Answer: Compares a group with an exposure to another group without an exposure and looks for differences in disease outcomes between the two groups.

Flashcard 6: What is the primary measure of association used in a cohort study?

Answer: Relative Risk (RR)

Extra: Cohort studies compare the incidence of disease in an exposed group vs. a non-exposed group to determine the Relative Risk (RR). In contrast: - Case-control studies use the Odds Ratio (OR). - Cross-sectional studies use Prevalence.

Flashcard 9: What is the equation for attributable risk percent in the exposed (ARPexposed)? _____

Answer: ARPexposed = 100 x [(RR-1)/RR]

Flashcard 10: The formula for Risk Ratio (RR) is _____.

Answer: [a / (a + b)] / [c / (c + d)]

Extra: Risk Ratio (RR) is used in **cohort studies** to compare the risk of an outcome in an exposed group vs. an unexposed group. **2x2 Table Layout:** - **a**: exposed, disease (+) - **b**: exposed, disease (-) - **c**: unexposed, disease (+) - **d**: unexposed, disease (-) RR = [a / (a + b)] / [c / (c + d)]
