Figure 1.

Coefficient curve of Turn 360 on (a) memory composite score, (b) processing speed/attention composite score, and (c) reasoning composite score. Note: Models were adjusted for sex, race, education, and self-rated health. The solid line was the coefficient estimate, and the light gray band was the 95% confidence band. Higher coefficient scores indicated a higher relationship magnitude. A coefficient band intersecting 0.0 indicated a nonsignificant (p > .05) relationship. Analytic sample sizes for each model were (a) n = 2,672, (b) n = 2,676, and (c) n = 2,676. The dashed lines represented the 95% confidence band for 85-year-olds. When any part of the gray band fell between the dashed lines, this indicated that for the corresponding age, the estimate was not significantly different than for 85-year-old participants.
