Abstract
This study aimed to analyze the 100 most-cited papers in Dentistry, with a focus on female leadership in dental research. Papers were retrieved from the Web of Science Core Collection (WoS- CC) in the category 'Dentistry, Oral Surgery & Medicine'. Gender was assessed through WoS-CC, Scopus, ResearchGate, social media, institutional websites, and software that assigns gender according to first names (https://genderapi.io). Characteristics of authors in leadership roles were retrieved, such as affiliation, publication history, citations, H factor, and i500. The 100 most-cited papers in Dentistry were authored by 394 researchers, 326 (82.7%) men, and 68 (17.3%) women - there were 4.8 male authors for each female. Among the lead authors, there were 11.3 males for each female. Among female senior authors, there were 7 males for each female. Among lead/senior authors of the 100 most-cited papers (first and last authors, respectively), 18 were women. There was an increase in the participation of women in the top cited papers regardless of authorship role across the six decades, with a peak of two female authors in the first decade of the 21st century. For female authors in leadership roles, their publication history shows the time between their first and last papers in WoS-CC ranged from 4 to 42 years for lead authors and 1 to 39 years for senior authors. Women were found to be largely underrepresented as leaders of the 100 most-cited papers, highlighting pervasive gender inequalities in dental research publications.

Abstract
BACKGROUND Social media is a powerful tool that has empowered plastic surgeons to easily collaborate with one another and rapidly publicize research progression. The present study investigates the relationship between academic productivity and social media presence among both integrated and independent plastic surgery programs and their faculty. METHODS Plastic surgery programs on the American Council of Academic Plastic Surgeons website were included. Faculty were identified via review of each program's website. Following metrics of academic productivity were collected for each faculty member: h-index, i10-index, number of publications, and number of citations. Online review was then conducted to identify faculty and program Instagram and Twitter accounts, and the number of associated followers and posts. RESULTS Integrated plastic surgery programs were more likely to have an Instagram account (p < 0.001), have higher average faculty h-index (p = 0.027), i10-index (p = 0.027), and number of publications (p = 0.042). A number of Instagram followers were significantly associated with average faculty h-index (p < 0.001), i10-index (p < 0.001), and number of publications (p < 0.001). The number of posts on a program's Instagram significantly predicted average faculty h-index (p < 0.001), i10-index (p < 0.001), and number of publications (p < 0.001). Twitter followers were significantly associated with average faculty h-index (p = 0.0397), i10-index (p = 0.0432), and number of citations (p = 0.00737). CONCLUSIONS The present study reveals a correlation between metrics of social media popularity and academic productivity of plastic surgeons. We propose that Instagram and Twitter are effective tools with which plastic surgeons may not only publicize their clinical practice, but also rapidly disseminate important innovations among the medical community. Integrated plastic surgery programs and their faculty have significantly higher utilization of social media platforms. The number of followers and posts on a program's Instagram have a significantly positive correlation with average faculty's academic productivity. Social media platforms may empower academic plastic surgeons to disseminate their innovations on a larger scale.

[PMID: 37662667 PMCID: PMC10473913 DOI: 10.5312/wjo.v14.i8.641] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Revised: 06/08/2023] [Accepted: 07/07/2023] [Indexed: 08/17/2023] Open
Abstract
BACKGROUND East Asia is the most dynamic region in the world and includes three major countries: Japan, South Korea and China. Due to rapid economic growth, orthopedics research in East Asia has achieved great advances during the past 10 years. However, the current status of orthopedic research in Japan, South Korea and China is still unclear. AIM To understand the current status of orthopedic research in Japan, South Korea, and China. METHODS Journals listed in the ''Orthopedics'' category of Science Citation Index Expanded subject categories were included. The PubMed and Web of Knowledge electronic databases were searched to identify scientific publications from the selected journals written by researchers from Japan, South Korea and China. A systematic analysis was conducted to analyze orthopedic research articles published in the three countries based on the number of articles, study design, impact factors (IFs) and citations. Furthermore, we also ranked the top 10 countries worldwide with the highest publications in the past 10 years. Additionally, we ranked the top 10 countries with the highest number of publications in the world in the past 10 years. Statistical analyses were performed using SPSS 20.0 software (SPSS Inc., Chicago, IL, United States), and statistical results are given in Tables and Figures. The Kruskal-Wallis test and the Mann-Whitney test were used to detect differences between countries. The tendency regarding the number of articles was analyzed by curvilinear regression. A two-tailed P < 0.05 was considered significant. RESULTS From 2012-2021, a total of 144518 articles were published in the 86 selected orthopedic journals. During this period, the number of worldwide published orthopedic articles has shown an annual increasing trend. A total of 27164 orthopedic research articles were published by Japan, South Korea and China during the past 10 years; 44.32% were from China, 32.98% were from Japan, and 22.70% were from South Korea. From 2012 to 2021, the annual number of articles markedly increased in each of the three countries. Over time, the worldwide share of articles increased substantially in South Korea (3.37% to 6.53%, P < 0.001) and China (5.29% to 9.61%, P < 0.001). However, the worldwide share of articles significantly decreased in Japan (5.22% to 3.80%, P < 0.001). The annual total IFs of articles from China were well above those of articles from Japan and South Korea (36597.69 vs 27244.48 vs 20657.83, P < 0.05). There was no significant difference among the articles in the top 10 high-IF orthopedics journals published from those three countries [South Korea (800) > China (787) > Japan (646), P > 0.05]. CONCLUSION Over the past 10 years, China's scientific publications in orthopedic journals have shown an increasing trend. Considering the relative scale of the populations, Japan and South Korea have outpaced China with respect to quality.

Abstract
Bibliometric analyses are a well-established strategy for understanding the dynamics of publications. Aneurysmal subarachnoid hemorrhage (aSAH) is a hot topic in neurology and neurosurgery research. To perform a bibliometric analysis of recent publications within aSAH. Articles addressing aSAH published between 2017 and 2021 were included and had their information extracted from Scopus. A total of 2177 articles were included. The mean number of citations was 6.18 (95%CI = 5.77-6.59). 2021 and 2020 were the most prolific years. World Neurosurgery (N = 389/2,177 articles; 17,87%) was the leading publisher, and American Journal of Neuroradiology had the highest number of citations per article (14.82) among journals with ≥ 10 publications. Primary research (N = 1624/2177) predominated, followed by case reports (N = 434/2,177). Among secondary studies, systematic reviews (N = 78/119) surpassed narrative reviews (N = 41/119). USA led the number of publications (N = 548/2,177 articles; 25.17%), followed by China (N = 358/2,177 articles; 16.44%). High-income countries had a higher number of publications (N = 1624/2177) and more citations per article (6.84) than middle-income countries (N = 553/2177 and 4.25, respectively). There were zero articles from low-income countries. European and North American institutions had the greatest research impact. There was an increase in the number of published articles in the last few years (2020 and 2021). Many studies had a low level of evidence, whereas interventional studies were uncommon.

Abstract
Aims and Objectives To perform a bibliometric study to identify and evaluate articles associated with "orthodontic wires" indexed in six databases (PubMed, Embase, Cochrane, Scopus, Lilacs, and Google Scholar) from 2010 to 2022. Materials and Methods The search strategy in PubMed combined different medical subject heading terms with free-text words and was adjusted for each selected database. The retrieved documents were original English articles containing the keywords used in the search strategies related to orthodontic wires. Collected data consisted of journal name, nationality, field, JIF-2 and JIF-5, SJR, CiteScore, Q and H-index, and categorization of the study. Results In total, 417 articles were retrieved from the initial search. After the exclusion criteria, 257 articles remained. The most common theme was mechanical properties, with basic studies as the main categorization. Conclusions This bibliometric survey provides an overview of orthodontic wires publications that might help orthodontists to understand the tendency of the studies on this subject. The retrieved papers were published in 100 journals, including 15 orthodontic journals, mainly in the first and second quartiles. Europe and America were the continents with the highest number of papers. The United States was the country with the highest number of journals on the topic. AJODO presented the highest h-index among the retrieved orthodontic journals. Brazil represented the principal institutions of origin of the listed articles. There was a tendency to increase the number of publications on orthodontic wires over the years. These findings indicate that research on orthodontic wires is still contemporary and relevant.

[PMID: 37152935 PMCID: PMC10154597 DOI: 10.3389/fendo.2023.1136048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2023] [Accepted: 04/06/2023] [Indexed: 05/09/2023] Open
Abstract
Background Non-fasting lipid assessment can help predict cardiovascular disease risks and is linked to multiple diseases, particularly diabetes. The significance of non-fasting lipid levels in routine screening and postprandial lipid tests for potential dyslipidemia has not been conclusively determined. Various new lipid-lowering strategies have been developed to improve non-fasting dyslipidemia. Therefore, analysis of scientific outputs over the past decade is essential to reveal trends, hotspots, and frontier areas for future research in this field. Methods The Science Citation Index Expanded in the Web of Science Core Collection database was searched for publications related to non-fasting lipid research from 2012 to 2022. The regional distributions, authors, disciplines, journals, references, and keywords of the studies were analyzed using the bibliometric software VOSviewer and CiteSpace. Results A total of 4160 articles and reviews that met the inclusion criteria were included in this study. The output trend was established to be stable and the number of citation indices has been persistently increasing. A total of 104 countries/regions, 4668 organizations, and 20782 authors were involved in this research area. In terms of country, the United States had the largest number of publications (979). The University of Copenhagen was the most productive institution, publishing 148 papers. Professor Børge G Nordestgaard has made the most significant contribution to this field. Nutrients was the most productive journal while the American Journal of Clinical Nutrition was the highest co-cited journal. Analysis of co-cited references indicated that lipid-lowering strategies, statin therapy, high-fat meals, insulin resistance, physical exercise, and fructose were hotspots. Analysis of co-cited keywords revealed that apolipoprotein B, especially apolipoprotein B48, is becoming a key research focus. The keywords "gut microbiota" and "meal timing" were the most extensively studied. Conclusion The causal relationship between non-fasting dyslipidemia and diseases is currently being explored and the standards for non-fasting or postprandial lipid assessment are continuously being updated. Among the hotspots, lipid-lowering strategies are a potential research direction. Apolipoprotein B48, gut microbiota, and chrononutrition are the research frontiers. This initial bibliometric analysis of non-fasting lipids will enable researchers to monitor swift transformations and recognize novel concepts for upcoming research.

Abstract
Brazilian scientific production has been mostly developed (90%) by Brazilian universities, mainly graduate programs, which must be assessed and ranked by the Brazilian government for their maintenance. The Qualis system is used for this classification by valuing the scientific production of graduate programs, stratifying journals and assigning grades. Several Brazilian researchers affirm that the Qualis system is inaccurate and subjective because it is carried out by a group of researchers. This work aimed to propose methods to evaluate Brazilian scientific production in order to improve the assessment of graduate programs through multi-criteria methods in addition to Qualis. The application of different metrics presented results significantly different from Qualis, including the over valuation of journals with a low international impact factor. The proposed metrics considered: (i) web of science impact factor of the journals; (ii) Citations from articles; (iii) Citations of citations, i.e., a new metric; and (iv) H-Index for researchers. It was proposed the multi-criteria method, composed of the mentioned criteria, in addition to Qualis. For the sample of researchers, it was demonstrated that multi-criteria methods can assess scientific production more accurately. Therefore, they are more adequate to assess the Brazilian graduate programs, considering several internationally accepted criteria.

Abstract
BACKGROUND Instability in the upper cervical spine, although rare, can be devastating. This spectrum of conditions includes occipitocervical instability, atlantoaxial instability and atlantoaxial rotatory displacement. Knowledge of the literature can provide better understanding of disease processes and management, and aid in clinical decision making. The objective of this study was to perform a bibliometric analysis to formulate a comprehensive review of the most cited publications. METHODS A systematic search of the literature was conducted using the Clarivate Web of Science database. The search query was '"Atlanto-occipital dislocation" OR "atlanto-occipital dissociation" OR "atlantoaxial rotatory displacement" OR "atlantoaxial instability"'. The top 100 articles based on frequency of citation were included in our study. Data extracted from articles included frequency of citation, year of publication, country of origin, journal of publication, level of evidence and article type. RESULTS Our initial search yielded 257 results that met the criteria. Articles not pertaining to atlanto-occipital instability were removed. Citation frequency ranged from 15 to 195. The most cited article was "Traumatic Anterior Atlanto-Occipital Dislocation" published by Powers et al. in 1979. The most productive decade was 2000-2009 with 45 publications. All decades showed a progressive increase in the number of papers published except for 2010-2019. Overall, 19 countries contributed and the most productive was the United States (n=61). The articles found in our search were cited a total of 4,095 times (3,463 without self-citations) averaging 40.95 citations per publication. DISCUSSION The goal of a bibliometric study is to assess trends in a specific field of study, provide evidence for the impact of an individual or field of study's research, and highlight potential areas for future research. While the number of citations does not necessarily reflect publication quality, it reflects overall influence based on recognition by peers in the field. Publications from the last 20 years have emphasized the use of newer technologies such as computed tomography (CT) and magnetic resonance imaging (MRI) to aid in diagnosis. Our study highlights the lack of high-level evidence articles and underscores that our understanding of these conditions in both pediatric and adult patients is maturing.

Abstract
Background: Hydrocephalus is one of the most common brain disorders and numerous articles were published to address the clinical aspect and its management. This study aims to highlight the most influential work on hydrocephalus on bibliometric basis. Methods: A thorough search of Scopus database was performed using the word “hydrocephalus.” The 100 most cited articles were retrieved, and variables of importance were collected including the article’s title, 1st author affiliation, country of origin, year and journal of publication, article’s category, and citation count according to Scopus and Google scholar databases. Results: The 100 most cited articles were thoroughly analyzed. Publication dates ranged from 1946 to 2014, with most articles (45) published between 1998 and 2007. The mean number of citations per publication was 201 with total of 20,177 citations. The United States of America contributed half of the articles. The leading institution was the Canadian hospital for Sick Children University of Toronto having published 5 articles. Hydrocephalus in general and normal pressure hydrocephalus was the two major categories addressed with most studies fall under the topic of surgical management.

Transl Pediatr 2022; 11:411-422. [PMID: 35378958 PMCID: PMC8976684 DOI: 10.21037/tp-21-506] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2021] [Accepted: 02/11/2022] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND AND OBJECTIVE This review examines a promising new framework for analyzing outputs of pediatric research in the context of translational advancement. We demonstrate a method for evaluating the impact of an NIH Clinical and Translational Science Award's (CTSA) Pediatrics Program through publications that have emerged from supported research. The Georgia CTSA Pediatrics Program provides training, funding, and infrastructure to ensure that researchers have the resources to advance pediatric health. Internal evaluations found that research supported by this program is exceptionally impactful within the academic community and commands high interest within the lay community. Therefore, we examined the impact of this research in both traditional academic and broader community spheres using bibliometrics-the study of supported publications. Bibliometrics describe a pivotal stage in the translational process of bringing scientific discoveries to clinical/community use and include both academic citations and 'altmetric' or non-academic attention. These complementary approaches combine to shed light on the short- and long-term impact of the research on segments of the translational pipeline, including academic literature, community discourse, technological advancement, and public health policy. METHODS The authors identified a portfolio of 250 articles supported by the Georgia CTSA Pediatrics Program from 2007-2020. We utilized various bibliometrics to analyze both short-term attention, or 'splash' made by articles, and long-term influence, or 'ripples' made across both academic and public spheres. KEY CONTENT AND FINDINGS The short-term splash of the portfolio was indicated through publication in high-impact factor journals, peer faculty recommendations, and Mendeley readership, as well as by early altmetric attention in news stories, blogs, and Twitter posts. The portfolio's long-term ripples were demonstrated by high absolute and relative rates of academic citation and by downstream altmetric influence in public-facing documents, including Wikipedia articles, patent applications, and policy documents. CONCLUSIONS This article reviews a useful bibliometric methodology for illustrating the waves of impact made by pediatric research. Whereas splash provides a picture of early interest in a publication, a preliminary indicator of eventual utility and impact, ripples provide a measure of the cumulative influence of an article over time. Both reflect opportunities for a line of research to advance along the translational spectrum.

Abstract
ABSTRACT The Hirsch Index is a measure of academic productivity which captures both the quantity and quality of an author's output. A well-accepted bibliometric, the Hirsch Index still may be influenced by self-citation, which has been assessed in other medical and surgical specialties. This study aims to evaluate research output and self-citation in physiatry, establishing a benchmark for the field, in addition to identifying differences between physical medicine and rehabilitation subspecialties. This study identified physical medicine and rehabilitation residency and fellowship program directors and analyzed the number of publications, citations, self-citations, and h-indices. A total of 169 program directors were identified, and the mean number ± SD of publications, citations, and Hirsch Index for the cohort were 16.7 ± 29.5, 348 ± 753, and 5.7 ± 6.7, respectively. When self-citation was excluded, less than 2% of program directors (3 of 169) had changes in Hirsch Index greater than one integer, and none greater than two integers. The Hirsch Index remained unchanged for 90% (152 of 169). Spinal cord injury fellowship directors had significantly higher mean number of publications (28, P = 0.04), mean number of citations (672, P = 0.03), and Hirsch Index (9.2, P < 0.01; 95% confidence interval). Overall, self-citation is infrequent in physical medicine and rehabilitation, and spinal cord injury directors had more robust academic profiles.

Abstract
OBJECTIVES/HYPOTHESIS Quantity and quality of Otolaryngology-Head and Neck Surgery (OTL-HNS) research are increasing, yet patterns within Pediatric OTL-HNS publications are unknown. This study examines trends in the level of evidence of pediatric OTL-HNS articles over a 20-year period to quantify the growth and characterize contributing factors. STUDY DESIGN Review article. METHODS A retrospective review was conducted on 12 peer-reviewed OTL-HNS journals at three time-points: 1996, 2006, and 2016. Pediatric-specific OTL-HNS journals were selected; all were among the top 10 highest impact factor journals, with one pediatric-specific and one Canadian journal. Publication details, author characteristics, and study focus were collected. Papers were classified based on the Oxford Centre for Evidence-Based Medicine Levels of Evidence by two independent reviewers. RESULTS Of the 1,733 articles reviewed, 727 met inclusion criteria. A greater absolute number of pediatric OTL-HNS articles were published over the years studied: from 95 in 1996 to 359 in 2016 (P < .001). As well, the absolute number of high-quality studies has increased over the study period, from 28 articles in 1996 to 100 articles in 2016. However, the relative percentage of high-quality papers remained stable between 27.9% and 32.2% with an average of 29.7% (P = .89). Higher impact factor journals did not tend to publish higher-quality pediatric OTL-HNS articles (P = .48). CONCLUSIONS Over the past 20 years, there is no appreciable improvement in the proportion of high-quality publications in pediatric OTL-HNS; however, there is an overall greater number of high-quality papers within OTL-HNS literature. These findings likely relate to challenges of research within pediatric surgical specialties. LEVEL OF EVIDENCE NA Laryngoscope, 2021.

Abstract
In the present age, there is intense pressure on researchers to publish their research in ‘high-impact factor’ journals. It would be interesting to understand the trend of research publications in the field of pharmacology by exploring the characteristics of research articles, including research techniques, in relation to the journal’s key bibliometrics, particularly journal impact factor (JIF), the seemingly most mentioned metric. This study aimed to determine the characteristics and research techniques in relation to research articles in pharmacology journals with higher or lower JIF values. A cross-sectional study was conducted on primary research journals under the ‘Pharmacology and Pharmacy’ category. Analysis of 768 original research articles across 32 journals (with an average JIF of 2.565 ± 0.887) demonstrated that research studies involving molecular techniques, in vivo experiments on animals, and bioinformatics and computational modeling were significantly associated with a higher JIF value of the journal in which such contributions were published. Our analysis suggests that research studies involving such techniques/approaches are more likely to be published in higher-ranked pharmacology journals.

Abstract
The rate of anterior cruciate ligament (ACL) retear remains high and revision ACL reconstruction has worse outcomes compared with primaries. To make advances in this area, a strong understanding of influential research is necessary. One method for systematically evaluating the literature is by citation analysis. This article aims to establish and evaluate "classic" articles. With consideration of these articles, this article also aims to evaluate gaps in the field and determine where future research should be directed. The general approach for data collection and analysis consisted of planning objectives, employing a defined strategy, reviewing search results using a multistep and multiauthor approach with specific screening criteria, and analyzing data. The collective number of citations for all publications within the list was 5,203 with an average of 104 citations per publication. "Biomechanical Measures during Landing and Postural Stability Predict Second Anterior Cruciate Ligament Injury after Anterior Cruciate Ligament Reconstruction and Return to Sport" by Paterno et al contained both the highest number of total citations and the highest number of citations per year, with 403 total citations and 43.9 citations per year. The most recurring level of evidence were level II (n = 18) and level III (n = 17). "Clinical Outcomes" was the most common article type (n = 20) followed by "Risk Factors" (n = 10). The American Journal of Sports Medicine had the highest recorded Cite Factor with over 50% of the articles (n = 27) published. The most productive authors included R.W. Wright (n = 6), S.D. Barber-Westin (n = 5), F.R. Noyes (n = 5), and K.P. Spindler (n = 5). Historically, influential studies have been published in the realms of clinical outcome and risk factor identification. It has been established that revision ACL reconstruction has worse outcomes and more high-level studies are needed. Additionally, prospective studies that apply the knowledge for current known risk factor mitigation are needed to determine if graft tear rates can be lowered.

Abstract
BACKGROUND Citation rates are an important measure for the impact of articles. This study is the most comprehensive analysis of predictors for scientific neurosurgical research articles. METHODS Scientific articles published in 13 neurosurgical journals in 2015 were selected. Data collected included article subject, level of evidence (LOE), journal impact factor (IF), authorship, contributing centers, and study design. Citation counts were collected for each article in Web of Science (WoS) and Google Scholar (GS) 2.5 and 5 years after publication and Scopus 5 years after publication. A generalized linear mixed-effects model using the predictors of search engine, LOE, number of centers, number of authors, and IF was constructed to predict total citation count at 5 years. RESULTS A total of 2867 articles generated 39,190 citations in WoS, 61,682 in GS, and 43,481 in Scopus. The median number of citations per article was 10 (interquartile range [IQR], 14) in WoS, 15 (IQR, 20) in GS, and 11 (IQR, 15) in Scopus. On average, for every 1 citation in WoS, Scopus and GS identified 1.11 and 1.58 citations, respectively. Significant predictors of citation count in all databases 5 years after publication included search engine, LOE, number of centers, number of authors, number of countries, journal IF, and the month of publication (P < 0.05). The article subject (e.g., tumor or spine) did not significantly predict citation counts. CONCLUSIONS In the most thorough analysis of citation predictors in the neurosurgical literature, search engine, LOE, number of centers, number of authors, number of countries, journal impact factor, and month of publication influenced citations 5 years after publication.

Abstract
Background The number of citations of an article reflects its impact on the scientific community. The aim of this study was to identify and characterize the 100 most cited articles on lung cancer screening. Methods The 100 most cited articles on lung cancer screening published in all scientific journals were identified using the Web of Science database. Relevant data, including the number of citations, publication year, publishing journal and impact factor (IF), authorship and country of origin, article type and study design, screening modality, and main topic, were collected and analyzed. Results The 100 most cited articles were all English and published between 1973 and 2017, with 81 published after 2000. The mean number of citations was 292.90 (range 100–3,910). Sixty articles originated from the United States. These articles were published in 32 journals; there was a statistically significant positive correlation between journal IF and the number of citations (r=0.238, P=0.018). Seventy-nine articles were original research of which 37.9% were about results from randomized controlled trials (RCTs). The most common screening modalities in these articles were low-dose computed tomography (LDCT) (n=78), followed by chest X-ray radiography (CXR) and sputum cytology (n=11). The most common topic in these articles was screening test effectiveness. Conclusions Our study presents a detailed list and analysis of the 100 most cited articles published about lung cancer screening which provides insight into the historical developments and key contributions in this field.

Abstract
The aim of this study was to explore and analyze the main features of the top 100 most-cited original articles, systematic reviews (SRs)/meta-analyses (MAs) in the field of robotic surgery, through scientometric analysis. VOSviewer and Excel 2019 were employed to conduct this scientometric study. We found that the majority of original articles (72/100) were published during the 2000s, while the majority of the top 100 most-cited SRs/MAs (91/100) during the 2010s. The USA was the most dominant country (n = 78), Henry Ford Health System was the most productive institution (n = 10), and Menon M was the largest contributing first author (n = 5) of the top 100 most-cited original articles. The USA was the most dominant country (n = 33), University of Padua was the most productive institution (n = 9), and Ficarra V was the largest contributing first author (n = 4) of the top 100 most-cited SRs/MAs. The top 100 most-cited original articles in robotic surgery have focused on the feasibility, outcomes and learning curve of robotic surgery for various neoplasms and cancers. The top 100 most-cited SRs/MAs have focused on the differences between robotic surgery and other types of surgery, with respect to the learning curve, costs, outcomes and experience in treating neoplasms, cancer and other diseases. In the future, the formation of cross-institutional and cross-disciplinary cooperation teams should be promoted and corresponding regulations and standards for specific diseases should be developed to regulate and promote the development of robotic surgery.

Abstract
INTRODUCTION Research on clear aligner treatment (CAT) has increased in recent years. In this study, we aimed to perform a bibliometric and visualized analysis to identify and critically assess the 50 most highly cited articles on CAT. METHODS Web of Science was selected as a data source and consulted until March 2020 to identify all articles potentially relevant to the analysis. All the eligible articles were collected until 50 manuscripts were listed. Article-based parameters, journal-based parameters, and author-based parameters were registered to perform the bibliometric analysis. Keywords were automatically harvested from the selected articles to implement the visualized analysis. RESULTS The search identified a total of 378 articles; the total number of citations of the selected articles varied from 15 to 112. The average number of citations per year varied from 1.15 to 13.83. The predominant study design was clinical (31.7%). Over the 15 journals in which the most cited articles were published, the American Journal of Orthodontics and Dentofacial Orthopedics published the majority of those included in the list (14) and also received the greatest number of citations (671). A total of 195 authors contributed to the 50 most cited articles; a significant portion of them (26) were unaffiliated with academic institutions. A total of 184 keywords were gathered from the article list. CONCLUSIONS The number of citations on CAT is expected to grow steadily in parallel with the rising number of research projects. The present work identifies the most influential articles on CAT and their characteristics, placing emphasis on the journals, the authors, and the topics addressed.

García-Villar C, García-Santos JM. Bibliometric indicators to evaluate scientific activity. RADIOLOGIA 2021; 63:228-235. [PMID: 33593607 DOI: 10.1016/j.rx.2021.01.002] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2020] [Revised: 12/03/2020] [Accepted: 01/05/2021] [Indexed: 01/04/2023]
Abstract
Bibliometric indicators have been devised to quantify scientific production and to try to evaluate its impact in the community. In general, bibliometric indicators can be classified according to whether the unit of analysis is the author (individual or group) or journal. The most widely used indicators for authors are those that measure an individual author's production, such as the Crown index or the h-index and its derivatives (e-index, h5-index, and the absolute or Ab-index, among others). The bibliometric indicators devised to try to evaluate journal quality are associated with Journal Citation Reports (e.g., impact factor, field-weighted citation impact, Eigenfactor, and article influence) or with Scopus (Scimago Journal Rank (SJR), source normalized impact per paper (SNIP), and CiteScore). This article describes the main bibliometric indicators, explains how they are calculated, and discusses their advantages and limitations.

Childs Nerv Syst 2021; 37:587-597. [PMID: 32780272 DOI: 10.1007/s00381-020-04858-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2020] [Accepted: 08/06/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Craniosynostosis is the premature closure of cranial sutures and it continues to be a therapeutic challenge due to the diversity and complexity of the syndrome. Bibliometric analysis is a study of ranking citations and exploring the most impactful articles in a respective discipline. It also demonstrates the chronological trends of publications. METHODS In May 2020, we performed a title-specific search of the Scopus database using "craniosynostosis" as our query term without publication date restrictions. The top 100 articles in craniosynostosis were retrieved and analyzed. RESULTS The top 100 most-cited articles in craniosynostosis received a total 13,826 citations, and an average of 138 citations per paper. The publication dates ranged from 1920 to 2015, with a peak period of top publications between 1996 and 2005. The most common category is clinical, followed by neurogenetics. The top cited article received 540 citation counts and 19.29 citations per year. The USA was the most contributing country to the list. The Journal of Plastic and Reconstructive Surgery published the largest number of top cited articles. Neurosurgery as a specialty contributed to most articles in the list (27 articles). The institute who contributed the most was the Assistance Publique Hopitaux Paris. CONCLUSION Bibliometric analysis in craniosynostosis revealed major trend changes of research over the years, with a focus on neurogenetics and the different types of surgical corrections. The current collection of highly cited publications may assist physicians in gaining a better understanding of the evidence-based approach in craniosynostosis.

Abstract
BACKGROUND Cerebrovascular disease is the second leading cause of death worldwide and provides a heavy burden of disease in Southeast Asia (SEA). Contribution to the collective knowledge of this disease is necessary to address practice and treatment disparities. There is limited data on research productivity in the region. This study aimed to determine research productivity on stroke and other cerebral and spinal vascular diseases among the SEA countries and determine its relationship with bibliometrics, socioeconomic parameters, healthcare delivery indices, and burden of disease. METHODS A comprehensive literature search was conducted using five major healthcare databases. We included studies published until June 2020 on cerebral and spinal vascular disease with at least one author from SEA. Country-specific socioeconomic parameters, the burden of disease, healthcare delivery indices, and the number of neurologists were collected from international databases and published data. Correlational analysis was done on bibliometric indices and collected data. RESULTS A total of 2577 articles were included. Singapore had the most publications (n=1095, 42.5%) and citations (PlumX n=16,592, 55.2%; Scopus n=22,351, 56.7%). Gross domestic product per capita, percent gross domestic product for research and development, universal health care effective coverage index overall and for stroke treatment, and the number of neurologists had a positive correlation to bibliometric indices. CONCLUSIONS There is a disparity in stroke research productivity among high-income and low-income countries in SEA. Priority must be given to scientific research output and its role in socioeconomic development and policy formulation.

Abstract
We compared the characteristics of the most cited, most downloaded, and most mentioned (the highest Altmetric Attention Score) articles published in general medical journals. We identified the 640 most frequently cited, 662 most frequently downloaded, and 652 most mentioned articles from 48 general medical journals. A comparison was made of the following characteristics of articles in the most cited, most downloaded, and most mentioned articles: medical specialty, publication type, country of origin, year of publication, and accessibility. There was only a 2.5% overlap in these three groups. Original articles were the more frequent among the most mentioned articles, whereas reviews, case reports, and guidelines/consensus statements were more frequent among the most downloaded articles. The most cited articles were more frequently published in 2010 and before, whereas the most downloaded articles were published in 2017−2018. The most mentioned articles were more frequently open-access articles, compared to the most downloaded articles. The most cited were more frequently older, the most downloaded were more frequently recent and educational, and the most mentioned were more frequently original and open-access articles. The results of our study may provide insights into various measures of article impact.

Abstract
BACKGROUND Altmetrics (alternative metrics) have become one of the most commonly utilized metrics to track the impact of research articles across electronic and social media platforms. OBJECTIVES The goal of this study was to identify whether the Altmetric Attention Score (AAS) is a good proxy for citation counts and whether it can be employed as an accurate measure to complement the current gold standard. METHODS The authors conducted a citation analysis of all articles published in 6 plastic surgery journals during the 2016 calendar year. Citation counts and AAS were abstracted and analyzed. RESULTS A total of 1420 articles were identified. The mean AAS was 11 and the median AAS was 1. The journal with the highest mean AAS was Aesthetic Surgery Journal (31), followed by Plastic and Reconstructive Surgery (19). A weak positive correlation was identified (r = 0.33, P < .0001) between AAS and citations. Articles in the top 1% in terms of citation counts showed strong positive correlation between AAS and citation counts (r = 0.64, P = .01). On the contrary, articles in the top 1% of AAS had no significant correlation with citation counts (r = -0.31, P = .29). CONCLUSIONS Overall correlation between citations and AAS was weak, and therefor AAS may not be an accurate early predictor of future citations. The 2 metrics seem to measure different aspects of the impact of scholarly work and should be utilized in tandem for determining the reach of a scientific article.

Abstract
Bibliometric analyses may indicate the most active journals, authors, countries, institutions and specialties by evaluating the most cited articles in a given research field. To the authors' knowledge, there is no bibliometric analysis regarding neurocritical care research. Thus, the aim of this study is to analyze and to provide a scope of the current scientific production in this area. The 100 most cited articles in the neurocritical care research were retrieved from the research "(neurocritical) AND (care)" in the Scopus database. The variables collected and included in this analysis were: number of citations, article title, first author's name, year and journal of publication and its impact factor (IF), specialty, affiliation and country of the corresponding author at the time of publication, and category of the article. Also, these variables were assessed for primary research only. The articles were published in 34 different journals from 1995 to 2017, with a mean citation number of 109.36, ranging from 44 to 540. Neurocritical Care (23 articles in top 100 and 2190 citations, IF = 3.163) and Critical Care Medicine (20 articles and 2896 citations in top 100, IF = 6.630) were the journals with the greatest number of articles and citations, respectively. Neurocritical Care also had the highest number of primary research papers (15 articles, accounting for 850 citations). Excepting one article from Asia (Singapore) and one from Oceania (Australia), all the other 98 papers were from North America (67) or Europe (31). United States was the country with most articles (60, 35 primary research) and citations (6115) among the top 100. Columbia University (11 articles, being 7 primary research, and 915 citations) was the institution with the highest number of articles and primary research articles in top 100, whereas University of Heidelberg (6 articles and 1220 citations) was the most cited institution. Neurology was the specialty with the greatest number of publications in top 100 and the most cited one (57 articles and 5983 citations). The first author with the greatest number of publications as well as primary research articles was A. I. Qureshi (5 articles, being 4 primary research, and 660 citations), while the most cited was K. H. Polderman (2 articles and 749 citations). Fifty-nine publications were primary and 41 secondary research. Among primary research, treatment/management was the most frequent and most cited topics (33 articles and 4172 citations). To the authors' knowledge, this is the first bibliometric analysis regarding neurocritical care research. Our findings suggest that the neurocritical care research field is more prominent in North America and Europe, more frequently published in specific critical care journals and after 1994. The most discussed topic was related to treatment and/or management within neurocritical care.

Abstract
BACKGROUND The impact factor (IF) is the most commonly used bibliometric method for rating academic journals. However, the practice of journals' self-citation may artificially elevate the IF. Additional bibliometric methods including Eigenfactor scale, SCImago Journal Ranking (SJR), and corrected IF (cIF) have been created. Comparing general-interest and specialized orthopaedic journals, the aims of this study were to assess: (1) the effect of journal´s self-citation on IF; (2) differences in bibliometric analysis; and (3) to determine thresholds for monitoring self-citation practices by defining the self-citation in orthopaedic research (SCOR) Threshold. METHODS The journal citation reports and SCImago Journal and Country Rank databases were queried for orthopaedic journals from 1997 to 2017. The following bibliometrics were compared between general-interest and specialized journals: IF, cIF, Eigenfactor, self-citation rates, and SJR. A novel metric, the cIF ratio, was proposed to represent the relationship between a journal's IF and cIF. Thresholds for cIF were based on statistical outliers of cIF ratio within general-interest and specialized journals were calculated. Outliers were defined as data points that were greater than the third quartile by 1.5 times the interquartile range using the last 10 years studied (2007-2017). RESULTS Specialized orthopaedic journals had a higher median self-citation rates compared to general-interest journals (11.85% vs. 6.36%, p < 0.001). Overall, cIF ratio declined over study period, and general-interest journals had a lower cIF ratio than specialized journals (8.77% vs. 19.54%, p < 0.001). Overall, general-interest journals had more favourable values for the bibliometric indices studied compared to specialized journals The SCOR threshold for cIF ratio was determined as 25.4% for general-interest journals and 53.3% for specialized journals. CONCLUSION Overall, self-citation occurs at a higher rate in specialized versus general-interest orthopaedic journals. We propose the use of a cIF ratio along with the SCOR threshold as a tool to evaluate and monitor journal self-citation practices in orthopaedic research.

Abstract
BACKGROUND The scientific activity of neurosurgeons and neurosurgery residents as measured by bibliometric parameters is of increased interest. While data about academic output for neurosurgeons in the USA, the UK, and Canada have been published, no similar results for German neurosurgical residents exist. Within this study, we aim to evaluate the academic output of German neurosurgery residents in 35 academic residency programs. METHODS Data for each resident were collected from the departmental websites, Pubmed, and Scopus. Further analyses evaluated the relationship between publication productivity, sex, and academic degree (Dr. med.). RESULTS Data from 424 neurosurgery residents were analyzed. A total of 1222 publications were considered. A total of 355 (29%) of the 1222 publications were first-author publications. The average number of publications per resident was 2.9; the average h-index and m-quotient was 1.1 and 0.4, respectively. There was a statistically significant difference in academic output and h-index among neurosurgical residents with a doctoral degree compared with residents without such degree (5.3 vs. 1.3, p < 0.0001 and 2.0 vs. 0.5, p < 0.0001). CONCLUSION This is the very first study evaluating the academic output of neurosurgical residents in academic neurosurgical departments in Germany.

Abstract
BACKGROUND This study aims to examine potential disparities in scholarly performance based on sex, academic rank, leadership positions, and regional distribution of faculty in accredited Head and Neck Surgery fellowships in the United States. METHODS Online faculty listings for 37 accredited fellowships were organized according to academic rank, leadership position, sex, and institutional location. Academic productivity was measured with three bibliometric indices: h-index, m-index, and the weighted relative citation ratio. RESULTS A total of 732 faculty members were included, of which 153 (21%) were female. Fifty-eight males (89.2%) held leadership positions, compared to seven females (10.8%). There was no significant difference in overall productivity between male and female senior faculty. There were regional differences in productivity by sex. CONCLUSIONS Females are underrepresented in senior faculty and within three common leadership positions, although scholarly productivity for male and female senior faculty and for those in leadership positions is similar.

Abstract
BACKGROUND AND PURPOSE Endovascular thrombectomy (EVT) has revolutionized the management of acute ischemic stroke. Landmark clinical trials have shown EVT to be one of the most efficacious interventions in clinical medicine over the past 5 years. A method of recognition for an article in the scientific community is to use a citation rank list, in order to identify the seminal works in the academic medical literature. The objective of this study was to characterize the 100 most highly cited articles assessing endovascular management of acute ischemic stroke. METHODS We conducted a retrospective bibliometric analysis using the Web of Science Citation Index Expanded database for the most cited works in the endovascular management of acute ischemic stroke. Citation count was used to rank the top 100 articles, which were then analyzed for authorship, year of publication, subject, study type, level of evidence, and subject. RESULTS The mean number of citations was 245 (range 65-1726) and 394 on Google Scholar. The top 100 articles were cited an average of 43.9 times per year and published in 21 journals in the past two decades. The majority of papers (62) were classified as constituting levels 1, 2, or 3 evidence, and included 17 randomized controlled trials. Approximately two-thirds of the top 100 articles originated from the USA. CONCLUSIONS This study details the most cited articles in the endovascular management of acute ischemic stroke, and furthermore shows that a high proportion of level I evidence exists for this intervention.

Boyd CJ, Gentry ZL, Martin KD, Rais-Bahrami S. Factors Associated With the Highest and Lowest Cited Research Articles in Urology Journals. Urology 2018; 124:23-27. [PMID: 30528715 DOI: 10.1016/j.urology.2018.11.034] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2018] [Revised: 11/21/2018] [Accepted: 11/27/2018] [Indexed: 10/27/2022]
Abstract
OBJECTIVE To determine what factors of published urology research articles are associated with future citations. METHODS We identified all primary research articles published between 1997 and 2007 in Journal of Urology, British Journal of Urology International, Urology, and European Urology. Only 50 articles in this period had accrued 0 or 1 citation in a 10-year period following publication. We compared the characteristics of the articles in the low citation cohort to the 50 articles with the highest number of citations from the same journals and time period. Student's t tests, Wilcoxon rank-sum tests, chi-squared tests, and Fisher's exact tests were used to analyze the data with predetermined level of significance set to P < .05. RESULTS There were many significant differences between the 2 cohorts. When compared to the cohort of articles with 0 or 1 citation, highly cited articles were significantly more likely to be a clinical study, multi-institutional and multinational effort, and related to the field of urologic oncology. They were also significantly more likely to have a larger sample size, a statistically significant primary finding, more authors, more references, and more tables, as well as longer title, abstract, and overall manuscript word counts. CONCLUSION Very few articles published in the major urology journals accrued 0 or 1 citation over a 10-year period. This suggests that the vast majority of articles selected for publication are used for further future research. Nevertheless, there were distinct differences between the 2 cohorts, showing that certain factors are associated with articles being cited more frequently.

Abstract
Background and purposeAlternative metrics (altmetrics), based on mentions in online media, is a new tool that can help to identify the most influential articles to diverse public audiences. This article aimed to determine the 100 most mentioned articles in the field of neurointervention and to analyze their characteristics.Materials and methodsWe selected the 808 journals that were considered journals potentially publishing articles on neurointervention. We also selected articles using keywords. Using the Altmetric.com search tool, we identified the 101 most mentioned neurointervention articles based on the highest altmetric attention scores (AASs) within selected journals and articles. Each article was evaluated for several characteristics including AAS, number of citations, journal title, journal category, impact factor of the journal, year of publication, authorship, country, type of document, and topic.ResultsThe AASs for the top 101 articles ranged from 1586 to 39. Stroke published the largest number of articles (19.8%) followed by the New England Journal of Medicine (17.8%). The majority of articles were published in multidisciplinary journals (38.6%), were published in 2017–2018 (43.6%), originated from the USA (54.5%), were original articles (66.3%), and dealt with intra-arterial thrombolysis or thrombectomy for acute ischemic stroke (58.4%). Tudor G Jovin was the most prolific author, authoring 18 of the most mentioned neurointervention articlesConclusionsThis study presents a detailed list of the 101 most mentioned neurointervention articles in online media, thus providing useful information on the dissemination of neurointervention research to the general public.

Comparison of Impact Factor, Eigenfactor Metrics, and SCImago Journal Rank Indicator and h-index for Neurosurgical and Spinal Surgical Journals. World Neurosurg 2018; 119:e328-e337. [PMID: 30055360 DOI: 10.1016/j.wneu.2018.07.144] [Citation(s) in RCA: 35] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2018] [Revised: 07/15/2018] [Accepted: 07/16/2018] [Indexed: 01/07/2023]
Abstract
BACKGROUND In academic specialties such as neurosurgery, bibliometrics are often used to guide readers, academic institutes, and researchers to make objective assessment of journals. Recently, new indices have been developed to overcome the shortcomings of the widely used Impact Factor. The objective of our study was to investigate the correlations among 6 of the commonly used bibliometric indices (Impact Factor, SCImago Journal indicator, SCOPUS h-index, Google h-index, Eigenfactor, Article Influence Score) in neurosurgical and spinal surgical journals. METHODS A list of all neurosurgical and spinal surgical journals was compiled using the databases of SCOPUS, Clarivate Analytics (Thomson Reuters), and National Library of Medicine Catalog. Journals that are not surgically oriented, non-English journals, and nursing journals were excluded. Bivariate Spearman ranking correlation tests were performed. RESULTS Fifty-four journals were included, of which 14 were spine themed. High positive correlations were obtained among the bibliometric indices of neurosurgical (nonspinal) journals (P < 0.05 in all pairs). Median values were 1.54, 0.66, 53, 25, 0.0035, and 0.46 for Impact Factor, SCImago Journal rank indicator, SCOPUS h-index, Google h-index, Eigenfactor, and Article Influence Score, respectively. However, the correlations for spinal surgical journals were more variable, likely because of the small sample size. CONCLUSIONS Despite the different mathematical basis among the citation-based bibliometric indices studied, they have strong correlations in ranking neurosurgical journals. This study provides evidence that the newer indices may be used interchangeably with the Impact Factor in this context, and they may, theoretically, mitigate some the shortcomings of the Impact Factor.

Abstract
The biological and medical importance of hydrogen sulfide (H2S) has been recognized for decades. The aim of this bibliometric study is to analyze the quantity and quality of publications in H2S biology and medicine (H2SBM) based on the databases of Web of Science and Google Scholar. A total of 5881 publications published between 1990 and 2016 were analyzed. The number of H2SBM papers published before 2004 was below 100 annually, but thereafter this number rapidly increased and peaked in 2015 with more than 7-fold increase. All publications related to H2SBM research achieved a total h-index of 136 and were cited 123,074 times. The most published disciplines in H2S biomedicine research were the cardiovascular system (8.5%), neuroscience (6.5%), and gastroenterology hepatology (4.7%). The country with the greatest number of publications in the H2SBM research field was the USA with 1765 (30.0%) publications, followed by China with 995 (16.9%) publications and Japan with 555 (9.4%) publications. The top 3 most published institutes were National University of Singapore, Peking University in China, and University of Groningen in Netherlands. Nitric Oxide Biology and Chemistry was the most exploited journal for H2SBM publications with 461 articles, followed by FASEB Journal with 200 publications and Antioxidants Redox Signaling with 116 publications. The most highly cited publications and researchers in H2SBM research were also unmasked from this bibliometric analysis. Collectively, H2SBM publications exhibit a continuous trend of increase, reflecting the increased H2SBM research intensity and diversity globally.
