Fig 1. Scatterplots displaying the relationship between FA and age (A). FA decreases linearly with age (ß = 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 (ß = –24 seconds per 0.01 FA unit; 95% CI, 16–33 seconds per 0.01 FA; r² = 0.274; P < .001).
