Odds Ratios in Logistic Regression with Effect Modifiers

André Anderson Carvalho
Hi R Users...

I'm trying to get the Odds Ratios for Logistic Regression Coefficients and their confidence intervals when there are interactions, or effect modifiers, in the regression model. May anyone help me how to get them?

Thanks
