Note:—L, left; R, right; Max, maximum; GM, gray matter; WM, white matter.
The absolute difference is unaffected by the sign of the change from week 0 to week 12. The maximal decrease and increase from week 0 to week 12 is expressed as volume (with units of milliliters) and as percent change (with respect to baseline).
