Figure Lengend Snippet: A) Coefficient plot. Standardized regression coefficients (β, circles) with 95 % confidence intervals (bars) for every two-way interaction (mtDNAcn × TL, mtDNAcn × DNAm, DNAm × TL)and for the three-way interaction (mtDNAcn × DNAm × TL) across baseline cognition, longitudinal cognitive decline, CSF biomarkers, and MRI measures. Magenta denotes statistically significant interactions. B) mtDNAcn × TL on global cognition. Predicted baseline global-cognition z-score versus mtDNAcn, with telomere length held at –1 SD (red, “short”), 0 SD (blue, “average”), or +1 SD (green, “long”). C) mtDNAcn × DNAm on language ability. Predicted baseline language-ability z-score versus mtDNAcn, with DNAm-age acceleration fixed at –1 SD (red, “younger”), 0 SD (blue), or +1 SD (green, “older”). D) Three-way interaction on grey-matter volume. Each facet fixes telomere length at –1, 0, or +1 SD (left-to-right). Within each facet, lines depict the mtDNAcn–grey-matter-volume slope at DNAm–1 SD (red), 0 SD (blue), and +1 SD (green).
