It's my first post and I hope I posted in the right forum.

In my master thesis I use binary logistic regression:

a dichotomous variable as dependent variable, and four ratio scaled variables as independent variables.

2 of the independent variables turns out as significant predictors (Let's call them Var A and Var B.)

But there are doubts that there could be a mediation effect. As mediator Var A might affect the relation between Var B and the dependent variable.

Now to my question.

**How do I control mediators in a logistic regression? How does a mediation analysis in logistic regression work?**

In a linear regression you can residualize the influence, but I do work with a logistic regression. I paid attention to the correlation between Var A and Var B, which was moderate (0.5). But I am not sure, if that's enough of controlling.

I'm thankful for every answer.
