Odds ratio vs relative risk-The risk ratio In practice, risks and odds for a single group are not nearly as interesting as a comparison of risks and odds between two groups For risk you can make these comparisons by dividing the risk for one group (usually the group exposed to the risk factor) by the risk for the second, nonexposed, group This gives us the risk ratioThe 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 nonexposed group Once we know the exposure and disease status of a research population,

Odds ratios (OR) are commonly reported in the medical literature as the measure of association between exposure and outcome However, it is relative risk that people more intuitively understand as a measure of association Relative risk can be directly determined in a cohort study by calculating a risk ratio (RR)Relative risk, Risk difference and Odds ratio When the data to be analyzed consist of counts in a crossclassification of two groups (or conditions) and two outcomes, the data can be represented in a fourfold table as follows Several statistics can be calculated such as relative risk and risk difference, relevant in prospective studies, andFor instance, a relative risk of 70% corresponds to an odds ratio of 07/(107)=233 however, it is clearer to say to the layman that a certain risk factor "increases the probability of a disease by 70%" (relative risk) rather than that it "increases the
