Venn diagrams showing overlapping between drugs belonging to the four main clusters in each network. (1) represents cluster I for all four networks. (2) represents cluster II for the reference reversible/irreversible and the human reversible networks, cluster III for the human irreversible network. (3) represents cluster III for the reference reversible/irreversible and the human reversible networks, cluster IV for the human irreversible network. (4) represents cluster IV for the reference reversible/irreversible and the human reversible networks, cluster V for the human irreversible network.
