The 2nd edition of Research.com ranking of the best researchers in the
discipline of Medicine relies os data
combined from various data sources including OpenAlex and
CrossRef. The bibliometric data for estimating the citation-based metrics were
gathered on 21-12-2022. Position in the ranking is based on a
scientist's D-index (Discipline H-index), which
includes exclusively publications and citation
data for an examined discipline.

The focus of our Medicine research
Research.com’s best scholars ranking is a credible
account of leading scientists from the discipline of
Medicine, established by means of a detailed
study of 166,880 researchers discovered
from multiple bibliometric data sources. For the area of
Medicine, as many as 68936 scholars were
analysed.
What is D-index acceptance threshold for Medicine
The D-index threshold for including a researcher to be
examined is set to 70 if
the majority of of their publications are in the discipline of Medicine. The
inclusion requirements for scientists to be
considered into the ranking of top scholars are based on the D-index, ratio
of the contributions made within the selected field of study
as well as the awards and achievements of the scholars. The
D-index threshold for including leading scientists is
set as an increment of 10 depending on the total number of scientists
projected for each discipline whilst
ensuring that the top 1% of best researchers are
considered into the list. We expect a proximity of
30% or less between a researcher’s general H-index and their D-index.
Extra verification practices
Since our primary goal is to guarantee that only
credible scholars are included in
our ranking we are aware that raw data are never
supposed to be a complete means to assess the
contributions of scientists. This is why
we manually inspect every profile and cross-correlate it against publications in a
broad range of credible sources. Although it’s not a
factor impacting a researcher’s position in
our ranking, the amount of documents published in
prominent journals and conference proceedings should be a
credible secondary signal of their contribution to research in a
specific area of science. Position in the ranking is
based on each researcher’s D-index
according to information collected from OpenAlex and
CrossRef, which are the most credible and well-known bibliometric
databases of this kind open to the scientific community. A
detailed overview of our research policy
can be found on our
methodology page.
Our agenda
Our aim is to inspire scientists,
companies and administrative bodies
worldwide to investigate where top experts are heading
and to offer an opportunity for the entire scientific community to
get to know who the leading experts in specific
disciplines, in different countries, or even within research
institutions are.
