The first column (N _ori) represented the total number of proteins (nodes) in the normal not common (NNC1 and NNC2) networks, common (C1 and C2) and disease not common (DNC) networks, collected using various databases (described in result and discussion section), number of proteins in the largest connected cluster (N) and connections (N _c), the average degree (⟨k⟩), diameter (D), average clustering coefficient⟨CC⟩, the number of nodes having CC = 1 (N _{cc = 1}) and CC = 0 (N _{cc = 0}) for all the networks.
