Fig. 03 / Named together

The 12 names most often in the same articles as The PRRT. A line's weight, and the number by each name, is how many articles name both. Grey chords join the neighbours most often named together themselves (two articles or more). Circles are people and organisations, squares are mechanisms. Named together is all this shows: it is not a finding about what the relationship is.
