Figure 2.

Association between cerebrovascular response to moderate-intensity aerobic exercise and response inhibition performance predicted from the regression model in APOE4 carriers (n=20) (solid line) and noncarriers (n=50) (broken line). In APOE4 carriers, greater cerebrovascular response to exercise was associated with better performance on the Stroop response inhibition task (p<.001). In noncarriers, no relationship was observed (p=.112).

Results for this regression model are detailed in Table 3.
