The bipartite prescription network of patient P₁ and the resulting bipartite patient-sharing physician network of P₁’s prescribers (A) and depiction of the resulting unipartite network (B). (A) The bipartite patient-sharing network of P₁’s prescribers was calculated based on the extended patient population. (B) The thickness of tie represents the number of shared patients. The resulting care density is 1.83.
