Hi All,
We have a test that compared the benefit (data reading, numerical data) of two different treatments over a couple of time points (baseline, T1, T2, etc). There are also some other effects: test sites, gender, etc.
For primary objective, I used the "Fit model" and put the data reading as Y, treatment, baseline level, time point, gender, subject ID(random factor), some 2-factor interactions in the model and hit run. Then see if treatment is a sig effect overall and at each time point.
We notice the response size (i.e. change from baseline CFB) was smaller in data from test site A than test site B. And test site A baseline level mean is higher than that of test site B. So I want to understand from the data if sample with lower baseline would response more/ have a bigger CFB?
I repeat the Fit model, and put CFB in Y. The effect summary showed "baseline level" effect is sig as well as baseline level*treatment interaction. But when looking into the effect details, there's nothing to show under baseline level effects. All the items plot, student T are greyed. I couldn't learn if higher baseline leads to smaller or bigger CFB.
How to best explore this question and have some more detailed results/plots than just a p?
Thank you all
Diana
