A Web-based systematic review on traumatic spinal cord injury comparing the "citation classics" with the consumers' perspectives

Although the citation index of an article is not a direct measure of its quality or importance, it is a measure of recognition that may suggest its impact on the scientific community. This study was undertaken to examine the characteristics of the top 100 most frequently cited articles (so-called "citation classics") on traumatic spinal cord injury (SCI) that were published between 1986 and 2003, and to compare this selected professional literature with the consumers' perspective on the key issues in SCI research. The 100 top-cited articles on traumatic SCI were identified using the Internet database of the Science Citation Index Expanded and the Web of Science with the terms "spinal cord injury" and "spinal cord injuries." Meeting abstracts, letters, and editorials were excluded. No language restriction was applied. From a consumers' perspective, the areas of greatest interest for people with SCI as reported in two previous large-scale surveys include motor function, bowel and bladder control, sexual function, and pain. The final list of citation classics on traumatic SCI included 82 original articles and 18 article reviews, which were cited 146 times on average. Topics on basic science (63%) were more frequent than clinical studies (37%). The years of publication were distributed in a bell-shape curve with a peak between 1992 and 1994. North American and European centers (99%) led the list of the citation classics. Most of the top 100 most frequently cited articles on traumatic SCI (63%) explicitly focused on at least one of the topics of greatest interest to individuals with SCI. Motor function was the leading topic in the matching list between professional literature and consumers' perspective. This bibliometric analysis, for the first time, identifies the key features of the citation classics on traumatic SCI between 1986 and 2003, a period that represents one of an unprecedented increase in knowledge in this field. The 100 top-cited peer-reviewed articles have been predominantly focused on basic science SCI research indicating a need for greater bench-to-bedside translational studies in SCI research. Although the body of this top-cited professional literature mostly matches with the consumers' perspective, most of this research has been focused on motor function assessment and recovery following SCI.     

Bibliometric analysis of the top 50 most cited publications of the Journal of Clinical Orthopaedics and Trauma

BackgroundThe Journal of Clinical Orthopaedics and Trauma (JCOT) is one of the top three orthopaedic journals from India. We set out to analyse the top 50 cited articles from JCOT since indexing in PubMed and Scopus.MethodsWe looked into the bibliometrics of the top 50 cited articles and compared citations from PubMed and Scopus, and depicted outputs from VOS viewer analysis on co-authorship and keywords.ResultsTotal citations for top-cited articles were 1076 in numbers, with a maximum of 103.2016 and 2018 were the most productive years. The major contribution was from India with 74%, followed by the USA. New Delhi published maximally at 72%. Clinical topics and narrative reviews were the most common types of studies. Trauma and Adult reconstruction was the most common sub-specialities, and Level 4 was the most frequent level of study. The basic science and COVID-19 related articles received the maximum citations. The authors from Indraprastha Apollo Hospitals published the maximum number of top-50 cited articles in the JCOT.ConclusionsThere is a steady increase in the number of publications in the JCOT, with an increasing number of citation counts. Both the Indian and foreign authors have been publishing in this journal at a comparative rate. Although the citation counts in Scopus are more than those in PubMed for given articles, more than 80% of articles are listed in both databases as top 50 cited articles. The majority of top-cited articles belonged to trauma and adult reconstruction, level III studies, and narrative reviews.     

The top 100 cited of injury-international journal of the care of the injured: A bibliometric analysis

BackgroundWith nearly 50 years’ of development, Injury has become one of the leading journals in its specialty. The aim of this article is to identify, analyze the characteristics of the 100 most cited articles published by the journal to date.MethodWe searched the Thomson Reuters Web of Science Core Collection for citations of all articles published in Injury since its launch. For the Top 100 most frequently cited articles, title, author name, number of authors, publishing date, citation number, country of origin, institution, pages, number of reference, type of article, study topic, study design, funding source, and level of evidence of each clinical article were recorded and analyzed.ResultsOnly 50 self-citations were found in 12436 total citations of the top100 articles, fifty-four articles exceeded 100 citations. Total citations of the Top 100 articles ranged from 77 to 599. The Top 100 articles were published between 1973 and 2012, the mean authorship and institution number per paper was 3.92 and 1.84 respectively. The mean page number was 8.26 and the mean reference number was 45.2. England, Germany and Switzerland ranked the top three countries of origin. Among the T100 articles, there were 50 clinical studies, 5 basic researches, and 45 reviews. The most common study type was case series, and most common topics were bone reconstruction, trauma and bone fracture. The most common level of evidence was level Ⅳ.ConclusionsThis study may help researchers to find out the important information on the classic articles and provides useful insights for the authors who want to publish their research in Injury.     

Thromboprophylaxis across orthopaedic surgery: Bibliometric analysis of the most cited articles

PurposeOne of the most common adverse events after orthopaedic surgery, with a potential for subsequent serious morbidity and mortality is venous thromboembolism (VTE). Bibliometric analysis has been performed regarding many topics and across orthopaedics. As DVT prophylaxis is a major component of both orthopaedic surgery considerations and research, a bibliometric analysis in this area would prove beneficial in not only in understanding the research done in the field thus far, but would also direct future research efforts.MethodsThe Web of Science (WoS) database from the Institute of Scientific Information (ISI) was used to compile articles for bibliometric analysis using Boolean search: ((Orthopaedic1 OR Orthopaedic1) AND (thromboprophylaxis OR Thromboembolism OR Deep vein thrombosis OR thrombus OR embolism OR anticoagulation OR Embolus OR prophylaxis)).ResultsThe Top 100 cited articles included in the final list generated a total of 21,099 citations. The highest cited article was Prevention of venous thromboembolism by Geerts et al. published in Chest, which had a total of 2802 on WoS, and a calculated citation density of 215.54 of citations/years since publication. Comparing the overall citation against the year of publication there was a slight positive trend favoring more recent publications (R-value: 0.142; adjusted R-squared: 0.01; p = 0.16). Analysis of an articles Level of Evidence (LOE), 17 were grade with a level of I.ConclusionsOrthopaedic thromboprophylaxis is an ever-changing field that is at the forefront of orthopaedic literature. The significant trend favoring high quality research within orthopaedic thromboprophylaxis demonstrates the importance of this topic and there was a need for a guide to best understand the evolution of DVT prophylaxis.     

The fifty most cited Latin-American articles in the orthopaedic literature

Purpose

The number of citations of an article is a marker of its academic influence. Several medical specialties, including orthopaedics, have ranked the articles with more citations. We identified the 50 most cited orthopaedic articles from Latin-America and analyzed the characteristics that made them citable.

Methods

Science Citation Index Expanded was searched for citations of articles originated in Latin-America, published in any of the 63 journals in the category “Orthopaedics” from 1988 to 2013. We created a list ranking the 50 most commonly cited articles and determined the citation density (Citations/years since publication). Information noted for each article included authors, year of publication, country of origin, source journal, article type, and field of research.

Results

Latin-American countries were the origin of 1 % of orthopaedic articles. The top 50 most cited articles had between 29 and 150 citations (mean, 44.48); the citation density ranged from 1.43 to 15.5 citations/years (mean, 5.25). The articles were published in 19 of the 63 journals (11 general and eight sub-specialty journals), and all were published in English. Most articles (n = 29) were published in 2000 or later. The majority were clinical articles (n=40), and the most common fields were arthroscopy (n = 15) and hip surgery (n = 13). The top 50 articles originated mainly from Brazil (n = 20) and Argentina (n = 15).

Conclusions

This top 50 list displays articles that have become important references for the orthopaedic scientific community. Researchers may use this work to make their future publications more influential on future investigators.

A citation rank list has historically been used within a particular field to measure the importance of an article. The purpose of this article is to report on the 100 most cited articles in the field of spine.

Methods

Science Citation Index Expanded was searched for citations in 27 different journals (as of 30 November 2010) chosen based on the relevance for all cited spine publications. The top 100 most cited articles were identified. Important information such as journal, date, country of origin, author, subspecialty, and level of evidence (for clinical research) were compiled.

Results

The top 100 publications ranged from 1,695 to 240 citations. Fifty-three articles were of the lumbar, 17 were of the thoracolumbar, and 15 of the cervical spine. Eighty-one of the articles were clinical and 19 were basic science in nature. Level of evidence varied for the clinical papers, however, was most commonly level IV (34 of 81 articles). Notably, the 1990–1999 decade was the most productive period with 43 of the top 100 articles published during this time.

Conclusions

Identification of the most cited articles within the field of spine recognizes some of the most important contributions in the peer-reviewed literature. Current investigators may utilize the aspects of their work to guide and direct future spine-related research.     

Citation classics in main pain research journals

The number of citations of an article in scientific journals reflects its impact on a specific biomedical field and its recognition in the scientific community. In the present study, we identified and analyzed the characteristics of the 100 most frequently cited articles published between 1970 and 2010 in journals pertaining to pain research and related fields. These articles were identified using the database of the Science Citation Index (1970 to present). The most cited article received 3,017 citations and the least cited article received 302 citations, with a mean of 585 citations per article. These citation classics were published in six high-impact journals, led by Pain (84 articles). Of the 100 articles, 39 were observational studies, 25 were review articles, and 20 concerned basic science. The articles originated from 14 countries, with the United States contributing 47 articles; 67 institutions produced these 100 top-cited articles, led by National Institutes of Health of the United States (8 articles) and University College London (6 articles); 18 persons authored 2 or more of the top-cited articles. This analysis of the top citation classics allows for the recognition of major advances in pain research and gives a historical perspective on the scientific progress of this specialty.     

Top 100. Revisión de los artículos más citados sobre cirugía laparoscópica del páncreas

IntroductionThe number of citations is considered as an indirect indicator of the merit of an article, journal or researcher, although it is not an infallible method to determine scientific quality. Our goal is to determine the characteristics of the articles most cited about pancreas and laparoscopy.MethodsWe performed a search of all articles published in any journal about pancreas and laparoscopy until September 2019 and selected the 100 most cited papers. We recorded number of citations, journal, year of publication, quartil, impact factor, institution, country, authors type of paper, type of surgery, topic and area.ResultsThe top 100 citations account 10,970 citations in total. The journal with the most articles is Surgical Endoscopy and 2007 is the year with the highest number of articles in the top 100 citations. The percentage of publications from America and Europe are similar.Case series is the most frequently paper, outcomes/morbidity is the most frequently discussed topic, and distal pancreatectomy is the most frequently type of surgery.ConclusionsThis bibliometric study on pancreas and laparoscopy is conditioned by the time factor, since laparoscopy has arrived later at pancreatic surgery, probably due to the morbidity and mortality associated with pancreatic surgery and the need for a high specialization in this field. The literature is recent and scarce. More and better-quality studies are needed in this field.     

Bibliometric Analysis of the Top-Cited Articles on Unicompartmental Knee Arthroplasty

BackgroundUnicompartmental knee arthroplasty (UKA) has been proven to be an effective surgical technique for unilateral compartment osteoarthritis. The purpose of this study is to identify and analyze the top 100 cited articles in the field of UKA research.MethodsPublications on UKA from 1980 to 2020 in the Web of Science database were retrieved. The characteristics of the top 100 cited articles were analyzed, including information of publications and citations, level of evidence, and research interests.ResultsThe number of publications and citations increased over time. The majority of the highly cited articles were from the Nuffield Orthopedic Centre (Oxford, England) and the Brigham and Women’s Hospital (Boston, USA). Long-term outcome of UKA and comparison between UKA and TKA gathered most research interests. The most frequently occurring keywords were “survival” and “revision.” Since 2012, “life quality” and “robotics” have been used. There was no level I evidence, and most studies provided level IV evidence.ConclusionThere was a rising trend in publications and citations in the field of UKA research, the majority of them were from a few centers, and were low-level evidence. Most studies focused on the long-term outcomes of UKA; in recent years, patient satisfaction and navigation surgery have become new research trends.     

Citation classics in anesthetic journals

The number of citations an article receives after its publication reflects its recognition in the scientific community. In the present study, therefore, we identified and examined the characteristics of the top 100 most frequently cited articles published in anesthetic journals. These articles were identified using the database of the Science Citation Index Expanded (SCI-EXPANDED, 1945 to present) and the Web of SCIENCE(R). The most-cited article received 707 citations and the least cited article received 197 citations, with a mean of 283 citations per article. These citation classics were published between 1954 and 1997 in 5 high-impact anesthetic journals, led by Anesthesiology (73 articles) followed by Anesthesia & Analgesia (10), British Journal of Anesthesia (10), Anesthesia (6), and Acta Anaesthesiologica Scandinavica (2). Seventy-eight articles were original publications, 22 were review articles, and one was an editorial. They originated from nine countries, with the United States contributing 70 articles. Within the United States, California leads the list of citation classics with 25 articles. Twenty-nine persons authored two or more of the top-cited articles. The main topics covered by the top-cited articles are pharmacology, volatile anesthetics, circulation, regional anesthesia, and lung physiology. This analysis of citation rates allows for the recognition of seminal advances in anesthesia and gives a historic perspective on the scientific progress of this specialty. IMPLICATIONS: We performed a citation analysis to identify important contributions and contributors to the anesthetic literature. These classic articles have influenced many people and have brought to our attention the many important advances in anesthesia made during the last 50 yr.     

What to call spinal cord damage not due to trauma? Implications for literature searching

Abstract

Objectives

To illustrate the importance of multiple search terms and databases when searching publications on spinal cord damage not due to trauma. To develop comprehensive search filter for this subject, compare the results for 2000–2009 with the Medical Subject Headings (MeSH) and Emtree term ‘spinal cord diseases’ and determine changes in the number of articles over this period.

Design

Literature searches and search filter development.

Setting

Australia.

Interventions

Titles and abstracts searched in MEDLINE and EMBASE (2000–2009) for articles involving humans using search terms ‘non-traumatic spinal cord injury’ and ‘nontraumatic spinal cord injury’ (concise search). Develop comprehensive search filter for ‘spinal cord damage not due to trauma’ and compare the results with the MeSH term ‘spinal cord diseases.’

Outcome measures

Annual publications (2000–2009) identified in MEDLINE and EMBASE literature searches.

Results

Concise search identified 35 articles published during 2000–2009. More publications were identified using the term ‘nontraumatic spinal cord injury’ (n = 20) than ‘non-traumatic spinal cord injury’ (n = 16). Publications increased for both terms ‘spinal cord diseases’ (2000 = 279; 2009 = 415) and ‘spinal cord damage not due to trauma’ identified by the comprehensive search filter (2000 = 1251; 2009 = 1921).

Conclusions

Concise searches using terms ‘non-traumatic spinal cord injury’ and ‘nontraumatic spinal cord injury’ fail to identify relevant articles unless combinations of terms and databases are used. These are inadequate search terms for a comprehensive search. Further research is needed to validate our comprehensive search filter. An international consensus process is required to establish an agreed term for ‘spinal cord damage not due to trauma.’     

Research advances in the diagnosis and treatment of moyamoya disease: a bibliometric analysis

Moyamoya disease is a rare cerebrovascular condition involving stenotic carotid arteries and the formation of abnormal blood vessels. In this study, we aimed to characterize the key players involved in moyamoya research at the individual and institutional level and to identify the critical publications that have advanced our understanding of this disease. We performed a title-specific search of the Web of Science database using the search term “moyamoya” for publications dating from 1900 to April 2020. The 100 most frequently cited articles were obtained, screened for duplicates, and reviewed by 2 independent reviewers. These 100 articles were cited an average of 150 times each (range, 74 to 1,360 citations per article). Publication dates ranged from 1969 to 2016, with the largest number of publications (n=40) cited between 2000 and 2009. The article with the greatest number of citations (1,360 citations) was “Cerebrovascular ‘moyamoya’ disease: disease showing abnormal net-like vessels in base of brain,” by Suzuki and Takaku, published in the Archives of Neurology, 1969. Stroke published the greatest number of the most frequently cited articles (23 of 100). The institution that contributed the most articles was Tohoku University (16%); the majority of the most frequently cited articles originated in Japan (62%). We identified the 100 most cited articles on moyamoya disease over the past 51 years to recognize significant and impactful works. These results can be used as a guide to evaluate our current understanding of moyamoya disease and to direct future efforts.

     

Femoroacetabular Impingement and Labral Tear: From the Most Highly Cited Articles to Research Interests

ObjectiveTo highlight the characteristics of the most highly cited articles and propose the research interests over the past decades in the field of femoroacetabular impingement (FAI) and labral tear.MethodsThe ISI Web of Science database (Clarivate Analytics, New York, the United States) was utilized for the identification of articles on 15 December 2020. FAI and labral tear‐related articles (1138 articles) were retrieved, of which the 100 most‐cited articles (top 100) were identified. Subsequent analysis included citation density (citations/article age), authorship, institution, journal, geographic distribution, level of evidence, and theme.ResultsThe number of citations per article ranged from 66 to 1189 with a mean of 163.31. The majority of articles were published in the United States (all articles/top 100 = 655/57) and Switzerland (85/22). University of Bern (n = 10) was the most prolific institution. The journal with the most of articles was Arthroscopy: The Journal of Arthroscopic and Related Surgery. The most prolific coauthor (all articles) or first authors (top 100) was Domb (n = 109) and Philippon (n = 6), respectively. The evidence with the most articles is level IV (n = 41). The top three most popular topics of research article were outcomes of surgery (n = 23), imaging diagnosis (n = 18), and comparison of surgery (n = 8). The top four most prevalent themes of review were labral tears (n = 3), FAI (n = 3), comparison of surgery imaging diagnosis, and outcomes of surgery (both n = 2). Six keywords with the newest average publication year, including FAI syndrome (average publication year = 2019.50), patient‐reported outcomes (2019.43), femoroplasty (2018.60), clinical outcomes (2018.17), borderline dysplasia (2018.00), and capsule (2018.00). Five keywords with the highest average citations, including outcome (average citations = 88.50), alpha angle (58.00), complications (55.86), revision hip arthroscopy (49.00), and systematic review (46.14).ConclusionsOutcomes research is the most popular research interest and patient‐reported outcome instruments might be further and widely used in the emerging articles in the near future. The field of FAI and labral tear has shown an obvious trend of development and is steadily evolving. It could be predicted that there will be an increasing number of publications in the following years, with the United States and Switzerland maintaining leadership in this field.
