Scientific Knowledge of Rheumatoid Arthritis: A Bibliometric Analysis from 2011 to 2020

Abstract

Background Recently, research on rheumatoid arthritis (RA) has made rapid progress and grown rapidly. It is a challenge to comprehensively understand RA research and hotspots. The aim of this study was to explore the current status and research trends of RA through bibliometric analysis and to provide directions for future development. Methods Publications on RA from 2011 to 2020 were retrieved from the Web of Science Core Collection database (WoSCC). VOSviewer, CiteSpace and online bibliometric platform were used to analyze publication characteristics, including countries, institutions, journals, authors, core references, and keywords. Results A total of 17,037 publications were included. The publications steadily increased over the 10 years. The United States (3648 publications), with the largest proportion of publications and citations, was the largest contributor. Karolinska Institutet (508) and Annals of the Rheumatoid Disease (763) were the most active institution and journal, respectively. Emery P (193) and Tanaka Y (193) were the most prolific authors, and Smolen JS ranked first among the cited authors. The most cited reference focused on recommendations for the management of RA with synthetic and biological disease-modifying antirheumatic drugs. A co-occurrence network analysis revealed four highly connected clusters of keywords in RA research, including etiology, pathology, prognosis, biomarkers and treatment of RA. Conclusion The present study shows a systematic and comprehensive overview of the RA-related research in the past 10 years. Clinical trials on the long-term efficiency and safety of JAK inhibitors and other novel targeted drugs may be the potential research directions for future study in this field.

Current situation and trend of non-coding RNA in rheumatoid arthritis: a review and bibliometric analysis

“…Bibliometrics is an important method of quantitatively and qualitatively analyzing publications within a specific field via mathematical and statistical approaches ( 14 ). It aims to uncover the research hotspots and trends by acquiring, processing, and analyzing the data of countries, institutions, author, journals, and keywords ( 15 ).…”

Assessment of Intestinal Permeability and Inflammation Bio-Markers in Patients with Rheumatoid Arthritis

“…Rheumatoid arthritis (RA) is an incurable chronic inflammatory autoimmune disease that affects about 0.5–1% of the general population worldwide and is characterized by joint swelling, pain, the presence of autoantibodies (rheumatoid factor and anti-citrullinated protein antibodies (ACPA)), and subclinical signs of inflammation that result in aggressive synovitis and destruction of joint cartilage and bone [ 1 , 2 ]. The cause and pathogenesis of RA are still not completely understood, but are generally considered to be related to environmental and genetic factors [ 3 ].…”

Bibliometric Analysis of Global Research Landscape and Hotspots on Dysmenorrhea: Where are We Now?

“…The bibliometric analysis provides an excellent solution to systematically and quantitatively analyze large-scale publications, presenting the development history and scientific status. 18 It has been employed in various primary care and public health fields, including COVID-19, 19 chronic postsurgical pain, 20 rheumatoid arthritis, 21 and central sensitization. 22 Whereas bibliometric analysis in the field of dysmenorrhea is scarce.…”
