Each strip is that field's whole ranked pool, with the notch where Hellenic Red Cross 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 Hellenic Red Cross work in?

In 2022-now, 83% of research at Hellenic Red Cross is in Health Sciences, 9% in Life Sciences. Its largest fields are Medicine (79%), Biochemistry, Genetics and Molecular Biology (6%), Engineering (3%). It does 3.3× the world's share of Health Sciences.
