Descriptive measures of the HCV network structure. (A) Degree distribution of the HCV network (solid line) and expected power law distribution (dashed line). (B) Clique distribution by size in the HCV network (black bars) and in 10,000 randomly rewired graphs (gray bars) that keep constant the number of vertices and their degree (19). (C) Rc of the HCV network (solid line) and the average of 10,000 randomly rewired graphs (dashed line) (20). (D) Structural robustness of the HCV network. The x axis is the percentage of removed nodes, and the y axis is the percentage of the original global efficiency of the network (21). The dashed line shows the random removal of nodes (average of 100 random sequences of node removal). The solid line shows the removal of nodes with the highest betweenness centrality (22). After each node removal, the betweenness centrality of each node was recalculated.
