Citation and reference domesticity. Citation domesticity (left) represents the share of citations to the cardiovascular dataset coming from the same country as the country of the cited publications in the dataset; reference domesticity (right) represents the share of references in the publications of the cardiovascular dataset that have authors from the same country. The country codes highlighted in red indicate an increase in domesticity between 1992–1998 and 2006–2012. (Data sourced from Thomson Reuters Web of Science Core Collection.)
