Logistic regression in a repeated measure

josecorrente — Fri, 11 Oct 2024 14:39:11 GMT

Hi all

I have a case-control design with binary response repeated in 3 moments. I would like to get some reference about how analyse the main effects as well as obtain OR or RR. I guess in this case Rr is more appropriate due to longitudinal aspect of the design.

I´m using glimmix but I´m not sure if this is effective to get all information an how to interpret the results.

Thanks in advance for any help

José Eduardo

Whether you use a mixed model with GLIMMIX or a Generalized Estimating Equations model with PROC GEE, you can get odds ratio estimates for your categorical (in CLASS statement) by specifying them in an LSMEANS statement with the DIFF and ODDSRATIO options. If you specifically want to estimate relative risks, then see the available methods discussed in this note.
