From: Microstructural brain abnormalities in HIV+ individuals with or without chronic marijuana use
HIV+ participants showed lower regional fractional anisotropy (FA) than SN subjects on DTI. A Regions of interest automatically segmented for the FA measures that showed significant HIV effects are shown relative other structures. B Compared to SN participants, and regardless of MJ use status, HIV+ had lower FA in both right and left anterior limb of internal capsule (ALIC), left cingulate gyrus cingulum (CGC), left superior fronto-occipital fasciculus (SFO), and right sagittal stratum (SS). SN, HIV-seronegative nonuser group; SN + MJ, HIV-seronegative marijuana user group; HIV, HIV-seropositive nonuser group; HIV + MJ, HIV-seropositive marijuana user group. Red star: p value remained significant after Holm-Bonferroni correction for multiple comparisons
