Conclusion: The age-related differences in the overall number of connections vary by dyadic clustering, global efficiency, leverage centrality, and degree difference. More specifically, older adults are less likely to have connections between nodes with higher clustering, global efficiency, and leverage centrality values, and more likely to have connections between nodes with a greater degree difference (less assortative) than younger adults. The age-related differences in the overall strength of connections vary by dyadic leverage centrality. More specifically, older adults have stronger connections between nodes with higher leverage centrality values than young adults.
