Plots of the associations between walking and cognition (A–F): A walking vs. total score (TS), B walking vs. memory score, C walking vs. non-memory score, D midlife-initiated walking intensity vs. TS, E midlife-initiated walking intensity vs. memory score, and F midlife-initiated walking intensity vs. non-memory score. A–F were adjusted for potential covariates; mean cognition values are presented and error bars represent standard error
