Misinterpreting Odds Ratio in the Articles Published in Korean Journal of Family Medicine
BACKGROUND In reporting results of case-control studies, odds ratios are useful methods of reporting findings. However, odds ratios are often misinterpreted in the literature and by general readers. METHODS We searched all original articles which were published in the Korean Journal of Family Medicine from 1980 to May 2011 and identified those that report "odds ratios." Misinterpretation of o...
متن کاملآیا نسبت شانس برآورد مناسبی از خطر نسبی است؟
Relative risk (RR) and Odds ratio (OR) are two measures of risk which has been widely used in epidemiological studies. The cohort studies are designed to directly compute a relative risk, but the situation is somewhat more complicated in the case-control design. In these studies, the odds ratio gives a valid estimate of the effect size. There is not a serious problem if you don’t use of t...
متن کاملConverting an odds ratio to a range of plausible relative risks for better communication of research findings
The odds ratio is a common measure in medical research of the effect size comparing two groups (treatments or risk factors) in terms of an outcome that is either present or absent. However, the odds ratio is poorly understood. The relative risk (also called the risk ratio) is more intuitive, but cannot be obtained from case-control studies or (except in rare instances) logistic regressions. Bec...

متن کاملUnderstanding the odds ratio and the relative risk.
Both the odds ratio and the relative risk compare the relative likelihood of an event occurring between two groups. The relative risk is easier to interpret and is consistent with general intuition. Some designs, however, allow only for the calculation of the odds ration. Covariate adjustment is easier for an odds ratio. Finally, the odds ratio avoids ambiguity by being invariant to lthe labeli...
