hi all!

I'm working on a project looking at the effect of an intervention on a continuous outcome variable over time. There are 3 time points. The model I'm using is:

mixed outcome a##time, ||patient ID, noconstant residuals(exch) -->the outcome is displayed below.


Array

I can obtain the overall significance of the interaction using

contrast a#time

However this does not give me an effect estimate for the change in outcome over time. I can obtain the effect of the interaction at the different time points by adding contrast a#time, effect however this does not give me an overall effect estimate for the interaction term to report.

Any thoughts?

Thanks!
