a
There is no significant difference between the total brain volumes of the subjects with NF-1 and controls, but the area and length of the CC are larger in NF-1. The factor groupings are also presented pictorially in Fig 1.
b
P <.05 after the Bonferroni correction.
c
P < .05 before the Bonferroni correction (.05/10) only.
