OBJECTIVE To determine how often the odds ratio, as used in clinical research of obstetrics and gynecology, differs substantially from the risk ratio estimate and to assess whether the difference in these measures leads to misinterpretation of research results. METHODS Articles from 1998 through 1999 in Obstetrics & Gynecology and the American Journal of Obstetrics and Gynecology were searched for the term “odds ratio.” The key odds ratio in each article was identified, and, when possible, an… 
Misinterpreting Odds Ratio in the Articles Published in Korean Journal of Family Medicine
In reports published in the Korean Journal of Family Medicine, odds ratios are frequently used, but were misinterpreted in part of the reports, although decreasing trends over years were observed.
Misuse of Odds Ratios in Obesity Literature: An Empirical Analysis of Published Studies
It is suggested that when the magnitude of associations is of interest, researchers should carefully and accurately present interpretable measures of association—including RRs and risk differences—to minimize confusion and misrepresentation of research results.

A greater understanding of ORs and RRs allows readers to draw more accurate interpretations of research findings and should also look to see that a confidence interval is provided with any report of an OR or RR.
Converting Odds Ratio to Relative Risk in Cohort Studies with Partial Data Information
The proposed new methods can convert the odds ratio to the relative risk, if an odds ratio and/or a confidence interval as well as the sample sizes for the treatment and control group are available and can be utilized to approximate therelative risk based on the adjusted odds ratio from logistic regression or other multiple regression models.
Odds Ratio or Prevalence Ratio? An Overview of Reported Statistical Methods and Appropriateness of Interpretations in Cross-sectional Studies with Dichotomous Outcomes in Veterinary Medicine
The findings of this study indicate that although there are methods that directly estimate PR, many studies in veterinary science do not use these methods and misinterpret the OR estimated by the logistic regression.

This article illustrates the problem of difficult to interpret odds ratios using an example from the recent dermatology literature, as well as reviewing the definitions of odds and odds ratio and methods to convert odds ratios to relative risks.
Making sense of odds and odds ratios.
Odds and odds ratios are hard for many clinicians to understand and should probably be limited to case-control studies and logistic regression, for which odds ratio are the proper measures of association.
Odds ratio vs risk ratio in randomized controlled trials
Use of OR instead of RR in RCTs does not change the qualitative inference of results, however, the use of OR can markedly exaggerate the effect size in R CTs if misinterpreted as RR and, hence, has the potential to mislead clinicians.
Technical note: The risk ratio, an alternative to the odds ratio for estimating the association between multiple risk factors and a dichotomous outcome.
The objectives were to explain why the risk ratio (RR) is an appropriate measure of association when the outcome of interest is dichotomous and to outline an applied method for estimating the RR using currently available software.
A Most Odd Ratio:: Interpreting and Describing Odds Ratios.
Education, peer reviewer vigilance, and journal reporting standards concerning ORs may improve the clarity and accuracy with which this common measure of association is described and understood in preventive medicine and public health research.


What's the relative risk? A method of correcting the odds ratio in cohort studies of common outcomes.
This work proposes a simple method to approximate a risk ratio from the adjusted odds ratio and derive an estimate of an association or treatment effect that better represents the true relative risk.
Relationship between prevalence rate ratios and odds ratios in cross-sectional studies.
A formula is offered and some-examples are offered for a better understanding of the relationship between PRR and POR as a function of the prevalence of the disease and the exposure and the choice between POR or PRR ought to be based on epidemiological grounds and not on the availability of software tools.
The effect of hysterectomy on the risk of an abnormal screening Papanicolaou test result.
The reduced risk of Papanicolaou test abnormalities among women aged >/=50 years who have had a hysterectomy should be considered when individual patients are being counseled, screening guidelines are being formulated, and health care resources are being allocated.
Familial occurrence of dystocia.
Dystocia has a familial occurrence, suggesting a possible genetic factor explaining inefficient uterine action in women whose mothers, sisters, or twin sisters had dystocic labor during childbirth.
Applied Logistic Regression
Applied Logistic Regression, Third Edition provides an easily accessible introduction to the logistic regression model and highlights the power of this model by examining the relationship between a dichotomous outcome and a set of covariables.
Perinatal and Neonatal Outcome and Late Pulmonary Sequelae in Infants Born After Preterm Premature Rupture of Membranes
Early PROM seems to be a major obstetric and neonatal problem with pulmonary ramifications extending beyond the neonatal period, however, most of these infants can be saved.
