Reciprocated information sharing ties across all quitline organizations including NAQC (funders and providers are separate): Mapping Tobacco Quitlines in North America.
Note. Gray squares represent quitline providers; dark gray circles represent quitline funders; and the light gray triangle represents North American Quitline Consortium (NAQC) network administrative organization (NAO). Size of the node is indicative of betweenness centrality (i.e., reflecting the number of organizations a particular organization is connected to, which are not themselves directly connected). The NAQC NAO node is artificially reduced.
