This table shows how many relations between which entities occur per article in both data sets. PharmGKB has some relations between entities of the same type. CTD contains only relations between entities of different types. In order to keep the tables of both databases easily comparable, entities of type "chemical" from CTD are labeled with "Dr" (drugs).
