Figure 5.

PPI datasets assessment by gene expression profile correlation. The distribution of Pearson’s correlation coefficient of the expression profiles of underlying genes of different PPI datasets are given in this figure (x axis is the Pearson’s correlation coefficient, y axis is the number of PPIs). The bar at -1 in the charts here corresponds to PPIs where we do not have the expression profiles of their underlying genes.
