Ranked on their work in Transplantation alone: how many more of their papers here reached the world top 10% for their subfield and year than the 10% expected, among 253,543 ranked researchers with a paper here. Each paper counts once, so many strong papers outrank one famous one, and a long record of ordinary papers does not climb. Identities come from OpenAlex author disambiguation, which occasionally merges or splits people.

Transplantation research by country
The best places for Transplantation research inside each country, with that country's researchers and world standing.
Where is the best place to study Transplantation?
Among universities, judged by research, Harvard University, Stanford University and Johns Hopkins University score highest, combining standing in the field's ranking, citation excellence, specialisation, size, growth and international reach. Research strength is one signal when choosing where to study; it does not measure teaching.
One dot per university in the first ten of the table below, at the default weights. The upper left is the interesting corner: small places doing unusually strong work.
Universities only. The score blends standing (50%), citation excellence (20%), size (15%), specialisation (5%), growth (5%), international reach (5%), 2022-now; growth compares 2018-21 with 2022-25 and counts up to +20%, since a jump from a small base is mostly noise. Standing is the score in this field's institution ranking, three quarters over all time and a quarter 2022-now; excellence averages the two windows too. Four years alone undercount fields such as AI, where many conference and arXiv papers from 2022 on carry no affiliation in the data.
Every institution in Transplantation, country by countryIs Transplantation research growing?
Output in 2022-2025 was 14% higher than in 2018-2021, peaking in 2025. The fastest-growing topics are Renal Transplantation Outcomes and Treatments and Organ and Tissue Transplantation Research.
The same series as a ribbon: one cell per year, darker for more. The line above answers how much; this answers when.
Its share of all research
Growing output can still be a shrinking share: all of science grows. This is Transplantation as a percentage of every work published that year, 0.044% in 2024.
Fractional works of Transplantation over all fractional works that year. How the balance of science has shifted.
How much of it reaches the world top 10%
Year by year.
Of each year's works in it, the share that reached the world's 10% most cited for their field and year. A field is the world for its own topics, so there is no other line to hold it against.
Which topics inside it are moving
Growth and decline on one axis around a shared zero. Two lists side by side hide the thing that matters: whether the growth dwarfs the decline, or the other way round.
