Notes.

^aRatio denominators were sequential as follows: ICV/Height, Tissue and CSF/ICV, Cerebrum and Cerebellum/Total Tissue, Cortex, White Matter, and all Lobes/Cerebrum Tissue;

^bCovariates = age and socioeconomic status;

^cRatio values are multiplied by 100;

^dBonferroni Correction applied, p-values adjusted for multiple comparisons.
