Figure 3. Independent effects of HIV and aging on rs-fcMRI correlations.

Figure 3

Parallel best-fit lines with differing intercepts model the effects of HIV and aging on intranetwork composite correlation value in both (A) the default mode network (DMN) and (B) the salience (SAL) network showing that the effects of HIV and aging are independent for each network. (C) Similar lines model the independent effects of HIV and aging on internetwork DMN-SAL anticorrelation. For all composite values, the magnitude of functional correlations diminishes toward zero (dashed line) due to HIV and aging. However, no interaction was seen between HIV and aging.
