Fig. 5. Correlation analysis with FA value in right SLF masks and NP test results.

Region in pink represents right SLF mask in JHU WM tractography atlas. Inside this mask, regions that showed significantly decreased FA between HAND and HIV-IC groups on TBSS analysis are marked in red and was used as mask for ROI (A). Mean FA value in this ROI was correlated with NP test results. Correlation results are shown graphically in (B). K-AVLT = Korean version of Auditory Verbal Learning Test, NP = neuropsychological, TMT A = trail making test part A, TMT B = trail making test part B
