Hi all,
I have 19 subjects with a baseline and follow up T1 MRI which I have used VBM on. The follow up ranges from 1month to 3yrs later. I would like to map the sensitivity of grey matter loss to another variable 'trauma severity'. Is it possible to set up a GLM for a Reciever Operating Characteristic (ROC) curve analysis? Or is there another way to test whether trauma severity mediates grey matter loss between baseline and follow up?
Thanks in advance!
Casey
