Fig. 2.

Group differences in growth rates between healthy controls and COS patients. (A) Mean growth rates in the healthy controls are subtracted from the mean growth rates in the COS patients. There are some areas (red) where ventricular or cerebral spinal fluid space expansion is numerically greater in the COS patients, but these differences are not significant because of the large intersubject variations in these changes. (B) Some deep WM areas (red) show significantly slower growth in COS.
