Figure 4A & B. Two-way interactions (APOEε4 allele × HIV status) show that SN subjects with APOEε4 allele(s) had similar volumes in the amydala, pallidum and thalamus (4A) or larger volumes in the cerebellar white matter, cerebral white matter and global brain volume (4B) compared to the SN subjects without the ε4 allele. However, HIV subjects with the ε4 allele(s) had smaller volumes than HIV subjects without the ε4 allele or the SN subjects. All p-values are adjusted for age and eTIV.
