Mixed model with interactions

[May Blake]

Hello,

I have mouse data for 3 treatments including control. Each treatment was given at increasing doses, baseline (0), 1, 2, 3, 4 microliters. Then we measured systolic bp, diastolic bp and body weight. I would like to know how each treatment differs for the outcomes (Sysbp, Diasbp and weight) I would like to create interactions between treatment and doses.

I created the following code.
mixed Sysbp weight i.treatment i.group##c.Dose|| ID:

I get the following table;

Then I write the code for the margins,
margins treatment, dydx(Dose) pwcompare

And I get this table

I'm not sure how to interpret the margins. Is this saying that compared to treatment 1, treatment 2 was statistically significant and etc? Thank you in advance.

the -margin- outcome tabke is simpy echoing the results of the fixed part of your -mixed- model: just compare the two tables and you will see that all the results concerning the interactions are identical.
