I have a dichotomous outcome variable (ever disease) and a continuous exposure variable (chemical). I have already run the logistic regression for the ln exposure and gotten the odds ratio. However, because this exposure is fairly common, a per 1-unit increase doesn't tell you a whole lot. Therefore, I wanted to see if there was a way that I could see the change per IQR increase in my exposure variable. Thank you!

  • $\begingroup$ Why not? Just do the multiplication. Are you somehow limited in the information you have about the data? If so, what information do you have? $\endgroup$

  • $\begingroup$ Do you mean to compute the change in odds given the estimate of the odds ratio? $\endgroup$
