Each strip is that field's whole ranked pool, with the notch where Graduate Hospital sits in it, in the colour of the band that rank falls in. The track under the rate is the rate itself: it carries no average mark, because the average differs by field (from about 6% in Dentistry to 21% in Economics).

Which fields of science does Graduate Hospital work in?

In 2022-now, 45% of research at Graduate Hospital is in Health Sciences, 30% in Life Sciences. Its largest fields are Medicine (40%), Agricultural and Biological Sciences (21%), Social Sciences (8%). It does 1.7× the world's share of Life Sciences.
