Fig. 3: Weighted-degree analyses.

Mean (±SEM) weighted degree (‘strength’) of (a) all 300 nodes and of (b) nodes within the frontoparietal network, specifically. Weighted degree (a, b) was derived from thresholded matrices. There were no significant differences across groups (all p-values > 0.21). Comparisons reported here are between n = 37 cognitively declining individuals and n = 22 cognitively stable individuals. See Supplementary Tables 9 and 10 for complete summaries of statistics.
