Major Contributing Units
The major contributors to this research were the United States and China, with the United States accounting for 33.5% of publications and China for 17.0% over the 20 years. Among the top 10 institutions with the most publications, the United States and China account for three each. Northwestern University had the highest publication volume and citations in the area worldwide. In CRS and NPs research, cooperation and linkages between countries were already intense. All countries with more than ten publications were involved in international collaboration. Undoubtedly, it promoted the flourishing of CRS and NPs research. Although European countries had fewer publications than the United States and China, their contribution to the research cannot be ignored. Of the ten institutions with the most publications, three were from Europe. And the Ghent University Hospital received the second most citations, following Northwestern University.
Of those institutions with more than ten publications, we found that Chang Gung University, Padova University, and Chung Shan Medical University had never collaborated with other institutions, which may affect the continued development of these institutions. We call for broader collaboration among countries and institutions, leading to more CRS and NPs research breakthroughs.
A total of 428 journals published research on CRS and NPs over the 20 years, and the International Forum Of Allergy & Rhinology (IF=5.426, Q1) had the most publications, indicating that it is the most popular journal in this research. After compiling the top 10 journals regarding the number of publications, we noted that six journals are Q1 and four are Q2. The top 3 journals with the most citations were all high-impact journals in Q1. Although CRS and NPs belong to rhinological diseases, many articles were published in allergy and basic medicine journals in addition to rhinology journals.
