Relative risk and odds ratio are often confused or interchanged. Especially while coefficients in logistic regression are directly interpreted as (adjusted) odds ratio, they are unwittingly translated as (adjusted) relative risks in many public health studies. In that relative risks are useful in many thousands of applications, instead of odds ratio, we propose a software tool to easily convert from odds ratio to relative risks under logistic regression. Unlike adjusted odds ratio conditional on other confounders, adjusted relative risks may vary depending on other confounders in the logistic model so we also analytically examine the effect of those confounders on the adjusted relative risk.
