The results of correlation analysis between mean standardized rsfMRI values and NP test scores.

(A) The left panel shows the ROI of the primary sensorimotor area which showed significant difference in ReHo values between HAND and HIV-IC. Scatter plots depicted in the right panel show significant correlations between mean ReHo values in the ROI and NP test scores. (B) The left panel shows the ROI of the orbitofrontal cortex which showed significant difference in fALFF values between HAND and HIV-IC. Scatter plots depicted in the right panel show significant correlations between mean fALFF values in the ROI and NP test scores. (C) Scatter plots show significant correlations between NP test scores and the rsfMRI values where standardized fALFF values in the orbitofrontal cortex are subtracted from standardized ReHo values in the primary sensorimotor area.
