Hi all,   When I run a multilevel multivariable logistic regression model with random intercept and fixed effects, my 'Odds Ratio Estimates' table is presented. At the bottom of this table is the following: "Effects of continuous variables are evaluated as one unit offsets from the mean. The suboption AT changes the reference value and the suboption UNIT changes the offsets."   Now, I know that when presenting continuous variables in a logistic regression model, the OR means that for every one-unit increase in your continuous variable, the odds on the dependent variable increases by factor X.   However, the line in SAS talks about "one unit offsets from the mean."   Does anyone know what is meant by this? Why does this refer to the mean? And then how do you correctly interpret this OR?   Much appreciated for any insights     ... View more
