  1. The number of nodes (N) represents the number of physicians with that specialty in the Providence, RI physician network. The linchpin mean and SD for the observed network are presented alongside the linchpin mean and SD for 10 permuted networks where the network structure was constant but specialty was randomly assigned. SD, standard deviation
