Does Logistic Regression Control for Confounders?

The special thing about logistic regression is that it can control for numerous confounders (if there is a large enough sample size). Thus logistic regression is a mathematical model that can give an odds ratio which is controlled for multiple confounders.

How does regression control for confounding?

Including confounding variables in a regression model allows the analysis to control for them and prevent the spurious effects that the omitted variables would have caused otherwise. Theoretically, you should include all independent variables that have a relationship with the dependent variable.

How do you deal with confounding in logistic regression?

It states that when the Odds Ratio (OR) changes by 10% or more upon including a confounder in your model, the confounder must be controlled for by leaving it in the model. If a 10% change in OR is not observed, you can remove the variable from your model, as it does not need to be controlled for.
