NIHR Oxford BRC authorship network showing extensive collaboration between research themes and working groups (April 2012–March 2017). A (Left) core of the author (relationship) network with authors primarily associated with the work from ‘research themes’ (established groups, blue), and a smaller number of authors in ‘working groups’ (orange). Each node represents an individual author (size  =  number of publications), and the edges represent the degree of co-authorship between authors (sum of weighted edges). Network diagrams are filtered (removing nodes and connections with an edge weight  < 0.5) to aid visibility. B (Right) core of the author network (same network as Panel A), but coloured by author’s most common research group, showing extensive co-authorship across research fields
