Grey matter volume	−.04 (.56)
White matter volume	−.05 (.47)
Cortical Thickness	−.02 (.81)
Mean FA	.03 (.72)
Mean MD	.23 (<.01)
In Controls
Grey matter volume	−.21 (.17)
White matter volume	−.15 (.34)
Cortical Thickness	−.22 (.17)
Mean FA	.19 (.40)
Mean MD	−.26 (.25)
In PHIVs
Grey matter volume	<.01 (.96)
White matter volume	−.02 (.76)
Cortical Thickness	.03 (.70)
Mean FA	.04 (.70)
Mean MD	.28 (<.01)

For each correlation, a bivariate Pearson’s correlation r value is given with the p value in brackets. FA=factional anisotropy; MD=mean diffusion.
