Most influential country and institution
These publications came from 82 countries and 3,139 institutions. We set
the publication threshold to 10 publications, and 43 countries met the
criteria. The top 10 countries were distributed in Asia, North America,
and Europe, mainly in Europe (n=5), with the United States having the
highest number of publications (n=1248, 33.5%), followed by China
(n=631, 17.0%), Korea (n=293, 7.9%), and Belgium (n=272, 7.3%).
During these 20 years, the total number of citations of publications
published in the USA ranked first with 39027 (Table 1).
Based on the selection criteria, we visualized the number of
publications and inter-country collaboration networks for these 82
countries (Figure 2A). For example, The United States had close
collaborative relationships with Canada, England, and Germany. In
addition, we also mapped the geographical distribution of inter-country
collaborations (Figure 2B) and the publication density (Supplementary
figure 1).
As with the above criteria, 190 of the 3,139 institutions met our
criteria. The top 10 institutions were also located in Asia, North
America, and Europe, mainly in the United States (n=3) and China (n=3).
Northwestern University (n=1248) was the top institution in terms of the
number of publications, followed by Capital Medical University (n=631)
and Sun Yat-sen University (n=293). Meanwhile, Northwestern University
also achieved the highest citations. We analyzed the average year of the
publications for the top 10 institutions, with larger values for Harvard
Medical School (2019.4316), Capital Medical University (2018.4385), and
Karolinska Institutet (2018.043), implying that these three institutions
may have invested more in this research of CRS and NPs in recent years
(Supplementary table 1).
Similarly, we constructed a collaboration network among the 190
institutions and visualized the average year of the publications from
different institutions (Figure 2C). Most institutions with high
publication volume collaborated with other institutions, especially
within the same country. Some had many collaborating institutions, such
as Sun Yat-sen University.
