Figure 1. Correlation of lesion load/third ventricle width with cognition for high and low education.

Correlation for low education (25^th percentile: ≤11 years of education; blue triangles) r = −0.52; p<0.05/r = 0.33; p<0.05 (N = 27) vs. correlation for high education (75^th percentile: ≥14 years of education) r = −0.37; p<0.05/r = 0.12; ns (N = 36), including fit of linear regression lines.
