Saiseikai Shigaken Hospital

The fields where it stands highest, over all time, ranked among every institution above the floor in each field.

Each strip is that field’s whole ranked pool, with the notch where Saiseikai Shigaken 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 world mark, because the world rate differs by field (from about 6% to 21% in this record).

Where its research is concentrated relative to its size: Medicine takes 4.5× the share of its output that it takes of world research.
