1. Scatterplots displaying the relationship between FA and age (A).
Scatterplots displaying the relationship between FA and age (A). FA decreases linearly with age (β = 0.010/year; 95% CI, 0.007–0.013 year; r2 = 0.371; P < .001).B, FA and time to completion for the executive maze test. Higher FA is associated with faster completion of the maze, a relationship described by a linear trend (β = −24 seconds per 0.01 FA unit; 95% CI, 16–33 seconds per 0.01 FA; r2 = 0.274; P < .001).
