External Email - Use Caution Hi Mr/Mrs
We treated a group of patients. We performed volumetric analysis in freesurfer before and after treatment. Is it correct to take volumetric values directly into a paired test? Or should we perform statistical analysis after dividing all values before and after treatment by "Estimated Total Intra Cranial Vol"? Is normalization by doing this way?
