The value of connected components measures the number of networks obtained; the number of nodes represent the total number of molecules involved; the number of edges represents the total number of interaction found; the clustering coefficient is calculated as CI = 2nI / k(k −1) where nI is the number of links connecting the kI neighbours of node I to each other; the network diameter is the largest distance between two nodes; shortest paths is the measure of the number (and percentage) of shortest path within the network; the Average n° neighbours represent the mean number of connection of each node; the Char. path length gives the expected distance between two connected nodes; γ represent the exponent of power law y = ax^{γ}, r is the correlation coefficient, R^{2} the coefficient of determination of power law.
