Comparison of network properties between observed and random graphs and the zi-Pi distribution of nodes. Global efficiency a, avgL (average shortest path length) b, natural connectivity of complete graph c, and remaining natural connectivity after 20% nodes removed randomly d. The bar plots represent the results of observed networks, while the error bar plots represent the mean and 1.96-fold of standard deviation. In d, the error bar of bar plot represents the standard deviation of 100 times random removal from observed network. e The zi-Pi distribution of nodes in the six MENs. The vertical lines were 0.62 and the horizontal lines were 2.5, which represent the classification threshold of node roles
