I have a question about logistic regression.
I have 2 groups in my database defined by a variable named "ttt".
I want to compare one variable named "w36_oxy" between the 2 groups, with an adjustment with 2 variables "pre_ste" and "g_age".
I tried this but I am not sure it is the result I want :
summary(glm(as.factor(w36_oxy)~ttt+g_age+pre_ste, data=data_dysplasie2, family=binomial))
