Thanks,
what I mean is in order to quantify a treatment effect for the subjects
that received treatment at T0, you would need another scan before that
(Tminus1). You would need three time points:
group1: baseline, placebo, treatment
group2: baseline, treatment, placebo
you could then test if
Hi Martin
Thank you very much for your response! To clarify the design: There are 44
subjects, all have been scanned twice and thus have repeated measures of
cortical thickness. 22 subjects were first (T0) scanned 2 hours after a placebo
treatment. Some days later, the identical subjects were
Hi Martina,
so you don't have a baseline (no treatment) measurement? If you have a
treatment at T0, you mean during an interval before T0, right? But since
you did not scan before that treatment, you cannot quantify that change?
The design is not clear to me.
