Bibliometric Analysis of the 100 Most Cited Articles on Intervertebral Disk Research: From 1900 to 2017 Year

Publication Trends and Hot Spots in Cauda Equina Syndrome: A Bibliometric Analysis and Visualization of Current Research

BACKGROUND

Cauda Equina Syndrome (CES) is a relatively uncommon and complex disorder. Recently, there has been a surge in research on CES. Although the research directions are multifarious, the overall research trends are unclear at present. We aimed to identify the 100 most cited articles on CES and analyze the hot spots trends regarding CES related research by bibliometric analysis.

METHODS

Articles were obtained by conducting an English language search of the Web of Science Core Collection Databases with the keywords "cauda equina syndrome." The initial 390 articles returned from the search were analyzed by VOSviewer. Next, the top 100 most cited articles were further analyzed by title, authors, journal, year of publication, total citations, country of origin, institution, and keywords.

RESULTS

A total of 390 publications were identified. The top 100 most cited articles were listed in descending order of total citations (range: 196-11). These articles originated from 24 countries; among these countries, the United Kingdom contributed the most publications (n = 29). The most prolific journal was Spine (n = 27), and the University of Edinburgh was the most productive institution (n = 9).

CONCLUSIONS

The number of publications on CES increased steadily, with a stable rise in recent years. Some publications have been cited more than 100 times, indicating that these findings are widely accepted by relevant clinicians and contribute significantly to the knowledge of CES. This study represents the first bibliometric analysis and visualization of hot spots analysis and research trends on CES. We believe that this will aid clinical researchers in targeting future areas of research.

Bibliometric analysis of the top 100 most cited studies in apolipoprotein E (ApoE) research

The apolipoprotein E (ApoE) is a glycoprotein which plays a vital role in different inflammatory conditions and in the catabolism of lipids and triglycerides. The aim of this study was to identify and evaluate the top 100 most cited studies on ApoE research. A bibliometric study was conducted. On January 18, 2021, studies published on ApoE were searched in the Web of Science Core Collection database without any limitations. The obtained data were analyzed for a number of attributes using HistCiteTM and VOSviewer software. The search yielded a total of 16,242 results. Of the total retrieved results, the top 100 most cited studies were selected. The top 100 most cited studies on ApoE were published from 1977 to 2017 and were cited 86,181 times. Single study citations ranged from 426 to 6,327. The studies were published in 41 journals authored by 589 authors. The study "Gene dose of apolipoprotein E type 4 allele and the risk of Alzheimer's disease in late onset families" was cited 6,327 times. Mahley RW, Roses AD, and Saunders AM were the most prolific authors who published ten studies each. Most of the studies were published in Proceedings of the National Academy of Sciences of the United States of America. A total of 151 institutions were involved, and the USA was the most productive country. Our finding provides valuable insight on ApoE research which may be useful for researchers, academia, and funding agencies to identify new future research domains.
