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 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.
