9 Απρ 2014 · This document discusses different risk measures used in epidemiology, including relative risk, odds ratio, and attributable risk. Relative risk measures the strength of association between an exposure and disease based on prospective studies.
8 Αυγ 2020 · Relative risk is calculated as the incidence of an outcome in an exposed group divided by the incidence in an unexposed group. It is the preferred measure for cohort studies where the number of people at risk is known. Odds ratio is calculated as the odds of exposure in those with the outcome divided by the odds of exposure in those without the ...
19 Δεκ 2013 · This document provides definitions and examples of key concepts for estimating risk from epidemiological studies, including probability, odds, relative risk, and absolute risk. It discusses how relative risk is calculated from cohort and case-control study designs.
8 Relative Risk (Risk Ratio) Estimates the magnitude of an association between exposure & disease. It is important in the causation & in the policy of prevention.
Relative Risk (RR): A ratio of the probability of the event (outcome variable) occurring in the exposed (risk factor) group to the probability of the outcome occurring in a non-exposed (no risk factor) group.
1 The Odds Ratio (Relative Odds) In a case-control study, we do not know the incidence in the exposed population or the incidence in the nonexposed population.
