Risk among exposed to risk among non exposed is defined to be
- Relative risk
- Odds ratio
- Attributable risk
- None of the above
The Correct Option is A
Solution and Explanation
In the context of epidemiology, understanding different metrics for analyzing the risk associated with exposure is crucial. Here, we discuss the definition and application of several key terms.
When we talk about the risk among exposed to risk among non-exposed, we are referring to a measure used to compare the probability of a certain event or outcome happening among individuals who have been exposed to a specific factor versus those who have not. This measure is known as the Relative Risk (RR).
Relative Risk is crucial in understanding the strength of the association between exposure and outcome.
The formula for Relative Risk is:
Where:
- Pexposed = Probability of the outcome occurring in the exposed group.
- Pnon-exposed = Probability of the outcome occurring in the non-exposed group.
Given the question, the correct answer is Relative Risk because it directly addresses the ratio of risks between exposed and non-exposed groups.
