Dear All,
I would need help with interaction terms and lincom command with STATA 11. Let’s say that the model (random effects logistic regression) includes a binary covariate labelled “drug” (0/1), a continuous variable “visit” from 0 (baseline visit) to 24, and one interaction between these 2 covariates (p<0.05).
For the slope, i used the following lincom syntax: lincom visit + c.visit#1.drug, or
Now, I would like to know the OR of drug use at visit 12. What would be the syntax for the lincom?
Thanks in advance for your help. All my best
Philippe
