Exercise training and chronic kidney disease: characterization and bibliometrics of citation classics of clinical intervention trials.

BACKGROUND: Exercise research targeting chronic kidney disease (CKD) has been conducted for more than 30 years, and the benefits of exercise for CKD patients have been progressively demonstrated. This study analyzes citation classics on clinical intervention trials on exercise training and CKD to describe the research landscape and hotspots through bibliometric analysis. METHODS: To identify clinical trials of exercise training interventions for CKD with more than 100 citations from the Web of Science Core Collection database. Extracted bibliometric information, participant information, and study characteristics of the included articles. The total citations, annual average citations, publication of year, author keywords, and study-related data were bibliometric analyzed and described using Excel 2019 and VOSviewer software. RESULTS: A total of 30 citation classics were included, with a total citation frequency of 102 to 279 (mean ± standard deviation: 148.4 ± 49.4). The American Journal of Kidney Diseases (n = 7) published the most (n = 7) classic citations in the field of CKD exercise research, and the Journal of the American Society of Nephrology was the most cited. The hotspot of research around CKD and exercise training interventions focused on population (hemodialysis and end-stage renal disease), exercise type (resistance training, yoga, and leg-cycling), and outcomes (cardiovascular indices, physical performance, psychological status, kidney function, physical activity). Reported dropout rates ranged from 0.0% to 47.4%. CONCLUSION: A bibliometric analysis of citation classics on exercise training and CKD highlights the potential benefits of exercise as a non-pharmacological therapy for patients with CKD, as well as developments and hotspots in the field.

The Top 100 Most Cited Publications on Suicide: A Citation Analysis.

Suicide is one of the leading causes of death globally and a matter of public health concern. Biomedical research on suicide has grown exponentially over the past few decades. Although numerous articles are published on suicide, only some exert significant influence in the evolution of scientific understanding. The number of citations a publication receives are a proxy marker of its impact on the field. Hence we aimed to analyze 100 top-cited articles on suicide till May, 2023, using Google scholar as the search database. These citation classics provide important insights into the historical development and trends in suicide research.

Research methodology used in the 50 most cited articles in the field of pediatrics: types of studies that become citation classics.

BACKGROUND: One of the frequently used methods for assessing research trends and the impact of published scientific literature in a particular discipline is citation analysis. Journals may strive to improve their metrics by choosing manuscripts and study designs that are more likely to be cited. The aim of this study was to identify the 50 most-cited articles in the field of pediatrics, analyze their study design and other characteristics of those articles, and assess the prevalence of systematic reviews among them. METHODS: In December 2017, we searched Web of Science (WoS) for all articles published in the field of pediatrics. Two authors screened articles independently and in the further analysis included 50 articles with the highest number of citations. To avoid bias for scientific papers published earlier, the citation density was calculated. We also analyzed Journal Impact Factor (JIF) of journals where citation classics were published. RESULTS: The citation density in top 50 cited articles in the field of pediatrics ranged from 33.16 to 432.8, with the average of 119.95. Most of the articles reported clinical science. Median 2016 JIF for journals that published them was 6.226 (range: 2.778 to 72.406). Half of the top 10 highly cited articles in pediatrics were published in a journal with JIF below 5. Most of the studies among the citation classics in pediatrics were cross-sectional studies (N = 22), followed by non-systematic narrative reviews (N = 10), randomized controlled trials (N = 5), cohort studies (N = 5), systematic reviews (N = 2), case-control studies (N = 2), case reports (N = 2), and there was one study protocol and one expert opinion. CONCLUSION: Few randomized controlled trials and systematic reviews were among citation classics in the field of pediatrics. Articles that use observational research methodology, and are published in journals with lower impact factors, can become citation classics.

Citation classics: the 100 most cited articles in Urogynecology.

INTRODUCTION AND HYPOTHESIS: The objective of this study was to utilize objective citation analyses to describe the 100 most cited articles in the field of Female Pelvic Medicine & Reconstructive Surgery (FPMRS) and to review their characteristics. METHODS: We searched the Thomas Reuters Web of Science database for the most cited articles within all journals classified as Obstetrics and Gynecology (Ob/Gyn), Urology (Uro), Colorectal Surgery (CRS), and vital General Medicine (GM) journals (New England Journal of Medicine; Journal of the American Medical Association; Lancet; The BMJ). We reviewed search results for FPMRS content and compiled a list of the top 100 most cited articles relevant to FPMRS. RESULTS: We screened 34,934 articles yielded by the initial search and compiled the 100 most cited articles relevant to FPMRS. Of these 100 titles, 40% (42 out of 105) were published in Ob/Gyn, 46.7% (49 out of 105) in Uro, 1.9% (2 out of 105) in CRS, and 11.4% (12 out of 105) in GM journals. The most cited FPMRS article was "The standardisation of terminology of lower urinary tract function: report from the Standardisation Sub-committee of the International Continence Society" (3,810 total and 242 citations per year). Over half the articles were observational in nature and the majority (58%) of them were related to urinary incontinence in women. CONCLUSIONS: Highly cited FPMRS articles come from a variety of journals, and nearly 50% of the 100 most cited FPMRS articles are from the urology literature. The most cited articles were largely observational rather than interventional studies and mostly related to female urinary incontinence.

A Bibliometric Analysis of Citation Classics in the Journal of Ultrasound in Medicine.

OBJECTIVES: A bibliometric analysis of articles in the Journal of Ultrasound in Medicine (JUM) identified the journals' most impactful articles. METHODS: A bibliometric analysis of citation classics that were published in the JUM from its inception in 1982 to 2019 was performed. All citation classics, defined as articles cited 100 or more times, were evaluated for the number of citations, citations per year, publication year, subspecialty, design, and country of origin. Characteristics were compared before and after 1998 by the Mann-Whitney test for unpaired data and 2-sample z tests of sample proportions. The Kruskal-Wallis test for nonparametric continuous data was used to compare the median number of citations per year by decade of publication. RESULTS: A total of 7868 articles were published in the JUM between 1982 and 2019; 54 (0.7%) were citation classics. The median citation classics year of publication was 1998 (interquartile range [IQR], 1991-2003). Most citation classics originated from the United States (36 of 54 [66.7%]), were observational (47 of 54 [87%]), and were related to obstetric and gynecologic topics (16 of 54 [29.6%]). Citation classics after 1998 received significantly more citations per year (9.3 versus 4.7; P < .001), with no other differences noted. The median number of citations per year increased for each decade, with medians of 4 citations (IQR, 3.6-4.7) in 1982 to 1991 and 11.2 citations (IQR, 9-13.9) in 2002 to 2012 (P < .001). CONCLUSIONS: This list provides insight into the most influential articles that were published in the JUM. Most citation classics were observational, were from the United States, and covered obstetric and gynecologic topics. Citation classics received more citations per year after 1998.

The Past, Present and Future of Literature Pertaining to Betel (Areca) Nut: A Citation Analysis.

Objective and method: Betel (areca) nut has recently received interest from researchers and policy makers for its role as a psychoactive substance. It was historically limited to Asia-pacific region, but with the advent of globalization, it has become an equally challenging public health problem across the globe. Previously published literature can give us valuable insights in terms of historical interest and understanding related to betel nut. With the expansion of biomedical research a huge number of articles have been published on the same. In terms of understanding the impact of an article, citations are considered a proxy estimate measure. Thus we decided to analyze the top 100 cited articles (till November 2018) related to betel nut. The search in Google scholar database was done with the help of freely available software, Publish or Perish. Results: Overall we found that most articles were published from the fields of dentistry and oncology, with relatively minimal contribution from the field of Addiction Psychiatry. Hence, most articles have addressed the issue of epidemiology and mechanism with lesser share of treatment related publications. Various important information related to these articles have been discussed including the institutions, countries, journals and impactful authors in the field. Subsequently, original research articles are further classified into descriptive/epidemiology, mechanism, management, scale/measurement, imaging and medical psychiatry. Importance: This citation analysis provides valuable information with regards to the emphasis of researchers in the field, and areas where more emphasis is required from contemporary world.

Top 100 Most Influential Articles in the Field of Myeloid Neoplasms: A Bibliometric Study.

BACKGROUND: Bibliometric analyses are a tool employed by researchers and funding agencies to establish the most important areas of research in a particular field, and to determine which foci need increased research attention. Such analyses have been published in a variety of clinical specialties; however, a detailed literature search showed that no such study has been done for "myeloid neoplasms." In order to bridge this gap, we conducted a citation analysis of the 100 most influential articles on myeloid neoplasms. METHODS: Two independent researchers extracted relevant articles from the Scopus database. These articles were then ranked in descending order of citations and a list of the top 100 original articles was made. A further, more detailed list was created containing significant discriminating characteristics. RESULTS: The top cited articles were published over a period of 47 years, with most of them being published in the 5-year interval of 2001-2005. The citations ranged from 636 to 4,039. The articles originated from 28 different countries. Most of the articles were published in high-impact journals. CONCLUSION: Our analysis sheds light on the quality of work and driving trends, listing the most cited and impactful guideline articles within this field and aiding clinicians.

The 100 top-cited articles focused on magnetic resonance: a bibliometric analysis.

BACKGROUND: The number of citations that an article has received can be used to evaluate its impact on a particular research area. PURPOSE: The aim of this study was to identify and characterize the 100 top-cited articles focused on magnetic resonance (MR). MATERIAL AND METHODS: We determined the 100 top-cited articles on MR via the Scopus database, using the search term. The following information was recorded for each article: year of publication; journal title; impact factor of journal; number of citations; number of annual citations; authorship; department; institution; country; type of article; topic; MR protocol; and disease. RESULTS: The number of citations for the 100 top-cited articles was in the range of 898-5679 (median = 1342.5) and the number of annual citations was in the range of 19.7-372.4 (median = 60.9). The 100 top-cited articles were published in 46 journals, led by Magnetic Resonance in Medicine (n = 13). The majority of articles were published in 1990-1999 (n = 53), originated in the United States (n = 69), were original articles (n = 81), and dealt with the clinical application of MR (n = 57). The Department of Radiology, Massachusetts General Hospital (n = 5) was the leading institution. The majority of articles did not use any specific protocol (n = 51) and was not associated with any specific disease (n = 56). CONCLUSION: Our study presents a detailed list and analysis of the 100 top-cited articles on MR, which provides an insight into historical development in this field.

Scientometric evaluation of the global research in spine: an update on the pioneering study by Wei et al.

PURPOSE: Wei et al. evaluated the global research in spine using scientometric methods based on a sample of 13,115 papers published in 5 spine journals from 2004 to 2013. This study builds on this pioneering study and provides up-to-date and thorough information on spine based on a sample of 166,962 papers for the stakeholders. METHOD: 'Articles' and 'reviews' published in 'English' in the journals indexed by the 'Web of Science' primary databases between 1980 and 2017 were retrieved through the use of an optimal keyword set for titles of both papers and ten spine journals. The information on document types and number of papers, authors, countries, funding bodies, institutions, publication years, journals, 'Web of Science' subject categories, and ten top citation classics were analyzed. RESULTS: A large sample of 166,962 papers were retrieved. The 'reviews' and 'proceedings papers' formed 5.8 and 2.8% of the sample, respectively. 'Fehlings', 'Vaccaro', 'Takahashi', 'Lenke', and 'Gokaslan' were the most-prolific authors. Nearly 0.7% of the papers had group authors besides single authors. The US was the most prolific country publishing 37.3% of the sample whilst Europe contributed to more than 39.8% of the sample. Only, 26.6% of the papers disclosed research funding. Among 40,897 institutions, 'Harvard University' was the most-prolific institution whilst the US institutions dominated the top-institution list. The research output steadily rose from 1375 papers in 1980 to 9357 papers in 2016 whilst 69.2% of the papers were published after 2000. Ten spine journals published only 23.4% of the sample. 'Clinical Neurology', 'Orthopedics', 'Neurosciences', and 'Surgery' was the most prolific subject categories. The top citation classic was a paper by van der Linden et al. on ankylosing spondylitis. CONCLUSIONS: The optimal design of research sample made it possible to obtain nearly 13 times the size of the sample in Wei et al. as a true representation of the research in spine through the use of an optimal keyword set for the titles of both papers and 10 spine journals. However, despite the inefficient design of the incentive structures for the relevant stakeholders, the research in spine had expanded 6.8 times since 1980.

Systematic review on citation classics in minimally invasive gastrointestinal surgery.

BACKGROUND: The impact an article has on a specific field is manifested by its number of citations. The aim of this systematic review was to perform a citation analysis and identify the 100 most-cited articles in the field of minimally invasive (MI) gastrointestinal (GI) surgery. METHODS: The Institute for Scientific Information Web of Knowledge (1945-2017) was utilised to identify the top 100 most-cited articles in the field of MI GI surgery, using 19 distinct keywords. The data extracted were number of citations, time of publication, research topic, level of evidence, authorship and country of origin. RESULTS: Of the 100 most-cited articles, the number of citations ranged from 3331 to 317 citations. Most publications reported on bariatric surgery (n = 36), followed by oncology (n = 26) and hepatobiliary surgery (n = 15). The studies were published in 26 different journals with the top three journals being Annals of Surgery (n = 30), New England Journal of Medicine (n = 10) and Obesity Surgery (n = 9). The studies were conducted in 17 different countries led by the USA (n = 51), the UK (n = 9) and France (n = 6). Articles were published on all levels of evidence: level I (n = 20), Level II (n = 29), Level III (n = 8), Level IV (n = 29) and Level V (n = 14). CONCLUSION: The study revealed citation classics in the field of MI surgery. Interestingly, a high level of evidence was not significantly associated with an increased citation number.

Citation Classics in Stroke: The Top-100 Cited Articles on Hemorrhagic Stroke.

BACKGROUND: Stroke is a disastrous disease and a major health burden worldwide, especially in Korea. Hemorrhagic stroke (HS) accounts for approximately 20% of all the types of strokes. It is important to be able to evaluate stroke diagnoses and evolving treatments. OBJECTIVE: We aimed to identify the top-100 cited articles and assess a paradigm shift that occurred in the field of HS. METHODS: We searched all articles that had been cited more than 100 times using the Web of Science citation search tool during January 2016. Among a total of 2,651 articles, we identified the top-100 cited articles on HS. RESULTS: The number of citations for the articles analyzed in this study ranged from 1,746 to 211, and the number of annual citations ranged from 125.6 to 5.5. Most of the articles that were published in Stroke (35%) and Journal of Neurosurgery (22%), originated in the United States (n = 56), were original articles (64%), and dealt with the natural history or etiology (n = 37) and vasospasm in subarachnoid hemorrhage (n = 8). CONCLUSIONS: We analyzed the top-100 cited articles in the field of HS based on citation rates. The results provide a unique perspective on historical and academic developments in this field.

The Web of Science search tools were used to identify the 100 most-cited articles relevant to neuroimaging within the selected journals. The following information was recorded for each article: publication year, journal, category and impact factor of journal, number of citations, number of annual citations, authorship, department, institution, country, article type, imaging technique used, and topic. The 100 most-cited articles in neuroimaging were published between 1980 and 2012, with 1995-2004 producing 69 articles. Citations ranged from 4384 to 673 and annual citations ranged from 313.1 to 24.9. The majority of articles were published in radiology/imaging journals (n=75), originated in the United States (n=58), were original articles (n=63), used MRI as imaging modality (n=85), and dealt with imaging technique (n=45). The Oxford Centre for Functional Magnetic Resonance Imaging of the Brain at John Radcliffe Hospital (n=10) was the leading institutions and Karl J. Friston (n=11) was the most prolific author. Our study presents a detailed list and an analysis of the 100 most-cited articles in the field of neuroimaging, which provides an insight into historical developments and allows for recognition of the important advances in this field.

Top-100 cited articles on Guillain-Barré syndrome: a bibliometric analysis.

Since the first description of Guillain-Barré syndrome (GBS) 100 years ago, the concept of this syndrome has changed remarkably. The purpose of our study was to identify and characterize the most-cited articles that have contributed to advancing the understanding of GBS. Based on the database of Journal Citation Reports, we selected 554 journals that were considered as potential sources of reports on studies related to clinical neurology and general medicine. The Web of Science search tools were used to identify the most-cited articles relevant to GBS or other variants in the selected journals. Of the selected articles, 18 were review articles and the remainder were original articles or included only a few case series. Among the original articles, 13 described basic research associated with immunological pathogenesis involving anti-ganglioside antibodies. Most of the original studies (42/64, 66%) published after 1990 evaluated anti-ganglioside antibodies that mediated axonal GBS or Miller Fisher syndrome, with only a small number of the papers involving electrodiagnostic medicine (n = 4). Our bibliometric analysis has yielded a detailed list of the top-100 cited articles in the field of GBS.

H-classic: a new method to identify classic articles in Implant Dentistry, Periodontics, and Oral Surgery.

INTRODUCTION: The study of classic papers permits analysis of the past, present, and future of a specific area of knowledge. This type of analysis is becoming more frequent and more sophisticated. Our objective was to use the H-classics method, based on the h-index, to analyze classic papers in Implant Dentistry, Periodontics, and Oral Surgery (ID, P, and OS). MATERIAL AND METHODS: First, an electronic search of documents related to ID, P, and OS was conducted in journals indexed in Journal Citation Reports (JCR) 2014 within the category 'Dentistry, Oral Surgery & Medicine'. Second, Web of Knowledge databases were searched using Mesh terms related to ID, P, and OS. Finally, the H-classics method was applied to select the classic articles in these disciplines, collecting data on associated research areas, document type, country, institutions, and authors. RESULTS: Of 267,611 documents related to ID, P, and OS retrieved from JCR journals (2014), 248 were selected as H-classics. They were published in 35 journals between 1953 and 2009, most frequently in the Journal of Clinical Periodontology (18.95%), the Journal of Periodontology (18.54%), International Journal of Oral and Maxillofacial Implants (9.27%), and Clinical Oral Implant Research (6.04%). These classic articles derived from the USA in 49.59% of cases and from Europe in 47.58%, while the most frequent host institution was the University of Gothenburg (17.74%) and the most frequent authors were J. Lindhe (10.48%) and S. Socransky (8.06%). CONCLUSION: The H-classics approach offers an objective method to identify core knowledge in clinical disciplines such as ID, P, and OS.

External funding of obstetrical publications: citation significance and trends over 2 decades.

OBJECTIVE: The objective of the study was to identify the external funding status of the most frequently cited obstetrical publications (citation classics) and to assess trends in funded vs nonfunded manuscripts as well as each publication's type of external funding. STUDY DESIGN: For the first objective, the citation classics, which were reported in a previous publication, were reviewed to identify their funding status. For the second objective, all pregnancy-related and obstetrical publications from the 2 US-based leading journals, the American Journal of Obstetrics and Gynecology and Obstetrics and Gynecology, were reviewed to identify the funding status and trends between 1989 and 2012. RESULTS: Twenty-seven of 44 of the citation classics (61%) had external funding, whereas only 43% of the reviewed regular (non-citation classic) obstetrical publications had external funding. There was a decreasing trend in the number of obstetrical manuscripts associated with a decreasing trend in the number and proportion of nonfunded manuscripts and an increasing trend in the number and proportion of National Institutes of Health (NIH)-funded manuscripts. Relative to 1989, in 2012 there was a 34.8% decrease in the number of published obstetrical manuscripts, a 59.6% decrease in the number of nonfunded manuscripts, and a 6.8% increase in the number of funded manuscripts accompanied by an 8.2% increase in the number of NIH-funded publications. In the last 9 years (2004-2012), there was a 35.1% increase in the proportion of NIH-funded manuscripts accompanied by an 18.8% decrease in the proportion of non-NIH-funded manuscripts. CONCLUSION: Our findings provide useful data regarding the importance of securing NIH-based funding for physicians contemplating academic careers in obstetrics.

The 100 most cited papers on total anomalous pulmonary venous connection: a bibliometric analysis.

BACKGROUND: The number of citations a paper receives reflects its impact on the scientific community. We aimed to identify and explore the characteristics of the most cited papers on total anomalous pulmonary venous connection (TAPVC). METHODS: Web of Science Core Collection Expanded Science Citation Index (1900 to present) was searched and papers on TAPVC were reviewed. Articles were ranked by the number of citations and the 100 most cited papers were analyzed. RESULTS: The 100 most cited papers were published between 1952 and 2018 with a mean number of citations of 52 (range 26 to 148). The 1990s was the most productive decade. All articles except one were written in English. The 100 most cited articles were published in 24 journals, led by Journal of Thoracic and Cardiovascular Surgery (21 articles), followed by Annals of Thoracic Surgery (20 articles), and Circulation (16 articles). The United States of America contributed most of the 100 most cited papers (60 articles). Hospital for Sick Children, Toronto led the list of citation classics with six papers. Christopher A. Caldarone, John W. Kirklin, and P. E. F. Daubeney were the most productive authors with 3 articles each. More than half of the papers were cohort studies (51 articles). Surgery, radiology and etiology were the main topics. Thirty-one articles were funded by public foundations, and none received support from commercial companies. CONCLUSIONS: The bibliometric analysis gives a historical perspective on scientific progress in the field of TAPVC and lays the foundation for future research.

A Bibliometric Analysis of the Literature on Norovirus Disease from 1991-2021.

Norovirus (NoV) is one of the oldest recognized diseases and the leading causal pathogen for acute gastroenteritis (AGE) worldwide. Though numerous studies have been reported on NoV disease, limited research has explored the publication trends in this area. As a result, the objective of this work was to fill the void by conducting a bibliometric study in publication trends on NoV studies as well as discovering the hotspots. The Web of Science central assemblage database was hunted for publications from 1991 to 2021 with "norovirus" in the heading. Microsoft Excel 2016, VOSviewer, R Bibliometrix, and Biblioshiny packages were deployed for the statistical analysis of published research articles. A total of 6021 published documents were identified in the Web of Science database for this thirty-year study period (1991-2021). The analyses disclosed that the Journal of Medical Virology was the leading journal in publications on norovirus studies with a total of 215 published articles, the Journal of Virology was the most cited document with 11,185 total citations. The United States of America (USA) has the most significant productivity in norovirus publications and is the leading country with the highest international collaboration. Analysis of top germane authors discovered that X. Jiang (135) and J. Vinje (119) were the two top relevant authors of norovirus publications. The commonly recognized funders were US and EU-based, with the US emerging as a top funder. This study reveals trends in scientific findings and academic collaborations and serves as a leading-edge model to reveal trends in global research in the field of norovirus research. This study points out the progress status and trends on NoV research. It can help researchers in the medical profession obtain a comprehensive understanding of the state of the art of NoV. It also has reference values for the research and application of the NoV visualization methods. Further, the research map on AGE obtained by our analysis is expected to help researchers efficiently and effectively explore the NoV field.

Top 100 Cited Articles on Clinical Hematopoietic Stem Cell Transplantation: A Bibliometric Analysis.

We conducted a bibliometric analysis to identify scholarly impact and factors associated with the top 100 cited articles on clinical hematopoietic stem cell transplantation (HSCT). In January 2021, a title-specific search was conducted. Non-HSCT and pre-clinical (in-vitro and animal) studies were excluded. A total of 39,406 records were identified and a list of the top 100 articles was made. Articles included in our study were characterized by the citations received, publication year, topic, study design, authors, h-index, and institutions. Linear regression analyses were performed. The 100 most cited articles were published over 52 years from 1968 to 2020, with a maximum number of articles (n = 40) published in the 1990s decade. Top-100 articles were cited 62,002 times with a median citation count of 465 (range 336-2240). The top-cited articles originated from 12 countries. United States contributed 69 articles. The University of Washington Fred Hutchinson Cancer Center (n = 15) was the leading institution. Blood (n = 32) and New England Journal of Medicine (n = 31) made the greatest contribution, and 52 manuscripts were clinical trials. The first author's H-index significantly correlated with citation count while journal impact factor, years since publication, first author's gender, and the number of authors did not have a significant association with the number of citations. In a multivariate regression model, the first author's h-index (regression coefficient 5.46, 95% confidence interval 2.99 to 7.93, p < 0.001) independently correlated with the citation count. Our study highlights the most influential articles on clinical HSCT and provides valuable insight for future research needs of the specialty.
