Obviously, these results run counter to expected results, putting the onus on the researcher to justify them. Similarly, you should find that increasing the incidence will increase the odds ratio. The relative risk and the odds ratio are measures of association between exposure status and disease outcome in a population. Relative risk In epidemiology, relative risk (RR) can give us insights in how much more likely an exposed group is to develop a certain disease in comparison to a non-exposed group. in a control group. The odds ratio (OR) is the odds of an event in an experimental group relative to that in a control group. An RR or OR of 1.00 indicates that the risk is comparable in the two groups.
Relative risk and odds ratio are often confused or misinterpreted.

As a reminder, a risk ratio is simply a ratio of two probabilities. (The risk ratio is also called relative risk.) Recently I have had a few questions about risk ratios less than one. A predictor variable with a risk ratio of less than one is often labeled a “protective factor” (at least in Epidemiology).

The direct computation of relative risks is A risk ratio (RR), also called relative risk, compares the risk of a health event ( disease, injury, risk factor, or death) among one group with the risk among another probability. Then we show how the effect of a disease risk factor, or a treatment, can be measured using the relative risk or the odds ratio. Finally we discuss the. 15 Feb 2012 Odds ratios (OR) significantly overestimate associations between risk factors and common outcomes. The estimation of relative risks (RR) or The relative risk.
