A scientometric study of oral cancer research in South and Southeast Asia with emphasis on risk factors control

Background/purpose

South Asia and Southeast Asia are the regions with relatively high and increased disease burden of oral cancer. The purpose of this study was to analyze the scientometric characteristics of oral cancer research in these regions.

Materials and methods

There are 8 countries from South Asia and 11 countries from Southeast Asia. All the articles on oral cancer from these countries were retrieved in the Scopus database.

Results

A total of 5660 articles originated from South Asia (n = 4718) and Southeast Asia (n = 942). India (n = 4302; 91.2%) was the country publishing most articles on oral cancer in South Asia, and Malaysia (n = 355; 37.7%) was first in Southeast Asia. Tobacco smoking, alcohol consumption, and areca nut as risk factors were common keywords, attention should be paid to them while developing polices for oral cancer control. In India, the most topic including distinctive keywords was diagnostics (sensitivity/specificity, saliva, and predictive value), followed by molecular biology (antioxidants, lipid peroxidation, and glutathione), experimental in vivo (hamster and cheek pouch), and risk factor (smokeless tobacco). In Malaysia, the most topic containing keywords was molecular biology followed by epidemiology and drug research.

Conclusion

This study for the first time reported the scientometric characteristics of oral cancer research in South Asia (India) and Southeast Asia (Malaysia). It is essential to improve the public awareness of risk factors control to reduce the oral cancer burden, especially in low-and middle-income countries.

Research Trends in Presurgical Infant Orthopaedic Treatment in Patients with Cleft Lip and Palate: A Bibliometric Analysis of 100 Most-Cited Articles

OBJECTIVE

To assess research trends and publication patterns of literature related to presurgical infant orthopaedics (PSIO) through a bibliometric analysis of the top 100 most-cited articles.

MATERIAL AND METHODS

The top 100 most-cited articles were identified in the Web of Science (WoS) database using search terms related to PSIO on April 23, 2024, without any restrictions to study design, publication date and language. Standard information about each study was extracted. Citations from WoS, Scopus and PubMed databases were compared. The level of evidence for each article included was assessed. Association between different variables was calculated using Spearman's correlation coefficient with statistical significance set at p < 0.05. Visual analysis of the author's keyword co-occurrence, co-authorship analysis of authors, and citation analysis of journals and authors were performed using VOSviewer.

RESULTS

Top cited articles were published from 1994 to 2020, with total individual database citations being WoS (n = 5378), Scopus (n = 6184) and PubMed (n =  10 450). Eleven articles were considered classic articles. Cleft Palate and Craniofacial Journal (Impact Factor = 1.1) had a maximum number of articles and citations. Two hundred eighty-five individuals contributed to top-cited articles, with 62 corresponding authors from 19 countries. A maximum number of authors were affiliated with universities in the United States. The most common keyword used was "nasoalveolar molding (n = 24)", "cleft palate (n = 16)", and "infant orthopedics (n = 16)". The study design of the majority of articles was retrospective and follow-up studies (level 3; n = 53). A weak negative correlation was observed between citation metrics and both the publication year (P < 0.01) and the level of evidence (P < 0.01).

CONCLUSION

This analysis recognises the contributions of experts and offers valuable insights into trends that have shaped the development and evidence related to PSIO research. Future research should focus on integrating advanced technologies, conducting longitudinal studies, fostering collaboration, and emphasizing patient-centred outcomes.

Methodological rigour in preclinical urology: a systematic review reporting research quality over a 14-year period

OBJECTIVE

To investigate the prevalence and trends of essential study design elements in preclinical urological studies, as well as key factors that may improve methodological rigour, as the demand for methodological rigour in preclinical studies is increasing since research reproducibility and transparency in the medico-scientific field are being questioned.

METHODS AND RESULTS

PubMed was searched to include preclinical urological studies published between July 2007 to June 2021. A total of 3768 articles met the inclusion criteria. Data on study design elements and animal models used were collected. Citation density was also examined as a surrogate marker of study influence. We performed an analysis of the prevalence of seven critical study design elements and temporal patterns over 14 years. Randomisation was reported in 50.0%, blinding in 15.0%, sample size estimation in 1.0%, inclusion of both sexes in 6.3%, statistical analysis in 97.1%, housing and husbandry in 47.7%, and inclusion/exclusion criteria in 5.0%. Temporal analysis showed that the implementation of these study design elements has increased, except for inclusion of both sexes and inclusion/exclusion criteria. Reporting study design elements were associated with increased citation density in randomisation and statistical analysis.

CONCLUSIONS

The risk of bias is prevalent in 14-year publications describing preclinical urological research, and the quality of methodological rigour is barely related to the citation density of the article. Yet five study design elements (randomisation, blinding, sample size estimation, statistical analysis, and housing and husbandry) proposed by both the National Institutes of Health and Animal Research: Reporting of In Vivo Experiments guidelines have been either well reported or are being well reported over time.

Re-irradiation Using Stereotactic Radiotherapy: A Bibliometric Analysis of Research Trends

The objective of this research is to conduct a comprehensive bibliometric analysis using the Web of Science Core Collection (WoSCC) to examine the current research topics and trends pertaining to stereotactic-based re-irradiation. A bibliometric search was conducted for re-irradiation-related literature published in English from the WoSCC database from 1991 to 2022, using VOSviewer to visualize the results. The extracted information comprises the publication year, overall citation count, average citation rate, keywords, and research domains. We conducted a literature review to identify trends in research on re-irradiation. A total of 19,891 citations were found in 924 qualifying papers that came from 48 different nations. The number of publications and citations has grown steadily since 2008 with the highest number of publications in the year 2018. Similarly, a substantial increase in the number of citations has increased since 2004 and the citation growth rate has been positive between 2004 and 2019 with a peak in 2013. The top authorship patterns were six authors (111 publications and 2498 citations), whereas the highest number of citations per publication was attained with an authorship pattern of 17 authors (C/P = 41.1). The collaboration patterns analysis showed that the largest proportion of publications emanated from the United States with 363 publications (30.9%), followed by Germany with 102 publications (8.7%), and France with 92 publications (7.8%). The majority of the analyzed studies were focused on the brain (30%), head and neck (13%), lung (12%), and spine (10%) and there have been emerging studies on the use of re-irradiation for lung, prostate, pelvic and liver utilizing stereotactic radiotherapy. The main areas of interest have changed over time and are now based on a multidisciplinary approach that integrates advanced imaging techniques, stereotactic treatment delivery, the toxicity of organs at risk, quality of life, and treatment outcomes.

Peri-implantitis: A bibliometric network analysis of top 100 most-cited research articles

BACKGROUND

Over the past decades, there has been an increase in research publications focusing on peri-implantitis. When facing limited healthcare resources, bibliometric analyses can guide researchers and funding parties toward areas where reallocation or more focus on research activity is warranted. The main objective of this study was to identify the trends of the top 100 cited articles on peri-implantitis research as the first study of its kind.

METHODS

A Web of Science search, using the keywords "peri-implantitis or periimplantitis" was built to create a database of the most-cited articles. Articles were ranked by citation count and screened by two independent reviewers. The bibliometric characteristics of the studies were gathered and analyzed using several bibliometric software. Author collaborations, author clusters, and keyword co-occurrence network analyses were also performed. The correlation between the citation count and the age of each article was tested.

RESULTS

The top 100 cited papers were published from 1994 to 2018 and the total citation counts ranged from 119 to 972 with 244.5 citations/paper on average. There was no correlation between the age of the articles and the citation count (p-value = 0.67). 21% of the studies consisted of prospective clinical studies. 35% of the papers focused on treatment and prevention of peri-implantitis while 65% concerned epidemiology. The top three most prolific countries were Sweden (n = 31), Germany (n = 15), and Switzerland (n = 13). We found 12 authors who had greater than five publications on the list. Also, the most published journal was Clinical Oral Implants Research.

CONCLUSION

This study provides insight into the characteristics and quality of the most highly cited peri-implantitis literature. This revealed a deficiency in terms of the number of studies on treatment strategies as well as a higher level of evidence studies among the most- impactful papers on peri-implantitis at the moment.

Top 100 Cited Publications in the Field of Temporomandibular Disorders: A Bibliometric Analysis

Background

The aim of this bibliometric research was to identify and analyze the top 100 cited publications in the field of temporomandibular disorders (TMD) in order to guide any professional level with interest in this topic by mapping the current trends in the field of TMD.

Materials and Methods

The Clarivate Analytics' Web of Science database was used to find the top 100 most cited papers in the field of TMD, published from the year 2000 to November 18, 2021, with MeSH terms in the search strategy. Data extracted were ranking, title, main author, institution, publication year, a total of citations, citation average per year, the journal the study was published, journal impact factor, and the number of studies that each journal published. Further, also the percentage of the different study designs, the number of studies regarding a specific area within the field of TMD, and the number of studies per country were also calculated. A ranking of authors was also performed.

Results

The top cited paper was a study on diagnostic criteria for TMD, with 1,287 citations published in 2014 in the Journal of Oral and Facial Pain and Headache which also had most of the top 100 cited publications. Eighty-one percent of the most cited studies were from the USA and Europe and 33% of the included studies were review articles.

Conclusion

Taken together, since all papers were considered classic, one can draw the conclusion that researchers in 2000 onward in the field of TMD are interested in (a) diagnostic criteria, (b) TMD symptoms and mainly pain-related symptoms, (c) etiology and risk factors of TMD and mainly bruxism, and (d) treatment of TMD. However, topics such as imaging, occlusion, tissue engineering, and disk displacements are presently not as popular.

Determining journal article citation classics in school psychology: An updated bibliometric analysis using Google Scholar, Scopus, and Web of Science

Bibliometric analyses have been the primary form of examining and evaluating literature within a field of study. By focusing on citation count and source, researchers have been able to identify journal articles considered to be high impact in reach and relevance, branding them "citation classics" in a field. As time progresses, technology, methods, and metrics for conducting these analyses have improved, and although there have been several studies designed to identify citation classics and patterns of citations supporting them in school psychology literature, none have done so in an updated, comprehensive manner. To address these limitations, the current study aims to replicate and extend these works in three major ways: (a) including 11 primary school psychology journals in the search, (b) using three of the largest reference databases, and (c) collapsing results across these databases to accurately identify the most highly cited articles. The search yielded evidence of more than 12,000 articles accruing more than 500,000 citations. The 100 most highly cited articles were identified, and the majority were classified as explicative (n = 63) and quantitative (n = 70). Themes of bullying, burnout, and teacher-child relationships were the prominent focus. School psychology's citation classics tended to feature quantitative research and examine the relations between constructs, and several revealed a new category of citations classics: the methodological and statistical article.

Top 100 cited systematic reviews and meta-analyses in the major journals of oral and maxillofacial surgery: a bibliometric analysis

The aim of this bibliometric research was to identify and analyze the top 100 cited systematic reviews in the field of oral and maxillofacial surgery in order to guide any professional level with interest in this topic and to map the current trends the field of oral and maxillofacial surgery. Using the Web of Science database without restrictions on publication year or language, a bibliometric analysis was performed for the five major journals of oral and maxillofacial surgery: International Journal of Oral and Maxillofacial Surgery (IJOMS), Journal of Oral and Maxillofacial Surgery (JOMS), Journal of Cranio-maxillofacial Surgery (JCMS), British Journal of Oral & Maxillofacial Surgery (BJOMS), and Oral Surgery, Oral Medicine, Oral Pathology and Oral Radiology (Triple-O). The most top-cited systematic review was published in 2015 with a total of 200 citations on survival and success rates of dental implants, consistent with the finding that "pre- and peri-implant surgery and dental implantology," and "craniomaxillofacial deformities and cosmetic surgery" were the most frequently cited topics (22% each). The majority of top cited papers were published in IJOMS (43%), followed by JOMS (34%), Triple-O (8%), JCMS(8%) and BJOMS(7%). The highest number of contributions was from the Netherlands, followed by Italy and USA. The outcome of this article can be used as a source of information and to guide not just researchers but also clinicians and students to which areas are trending in the field of oral and maxillofacial surgery, thus also having a large impact on the field of oral and maxillofacial surgery. However, this article cannot reflect the quality of the included systematic reviews.

Predicting the number of article citations on the topic of pemphigus vulgaris with the 100 top-cited articles since 2011: A protocol for systematic review and meta-analysis

BACKGROUND

Pemphigus vulgaris (PV) is a rare autoimmune blistering disease characterized by intraepithelial and mucocutaneous blister formation and erosion. Numerous articles related to PV have been published. However, which articles have a tremendous influence is still unknown, and factors affecting article citation numbers remain unclear. We aimed to visualize the prominent entities using the top 100 most-cited articles on the topic of PV (T100PV), and investigate whether medical subject headings (i.e., MeSH terms) can be used to predict article citations.

METHODS

By searching the PubMed Central (PMC) database, the T100PV abstracts since 2011 were downloaded. Citation analysis was performed to compare the dominant entities in article topics, authors, and research institutes using social network analysis (SNA) and Kano diagrams. We examined the MeSH prediction power against article citations using correlation coefficients (CCs).

RESULTS

The most cited article (125 times) was authored by Ellebrecht from the University of Pennsylvania in the US. The most productive countries were Germany (28%) and the US (25%). Most articles were published in J Invest Dermatol (16%) and Br J Dermatol (10%). Kasperkiewicz (Germany) and the Normandie University (France) were the most cited authors and research institutes, respectively. The most frequently occurred MeSH terms were administration and dosage, immunology, and metabolism. MeSH terms were evident in the prediction power on the number of article citations (F = 19.77; P < .001).

CONCLUSION

A breakthrough was achieved by developing dashboards to display the T100PV. MeSH terms can be used to predict the T100PV citations. These T100PV visualizations can be applied in future studies.

The 50 most-cited articles on clear aligner treatment: A bibliometric and visualized analysis

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.

Predicting the number of article citations in the field of attention-deficit/hyperactivity disorder (ADHD) with the 100 top-cited articles since 2014: a bibliometric analysis

BACKGROUND

Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in children or early adolescents with an estimated worldwide prevalence of 7.2%. Numerous articles related to ADHD have been published in the literature. However, which articles had ultimate influence is still unknown, and what factors affect the number of article citations remains unclear as well. This bibliometric analysis (1) visualizes the prominent entities with 1 picture using the top 100 most-cited articles, and (2) investigates whether medical subject headings (i.e., MeSH terms) can be used in predicting article citations.

METHODS

By searching the PubMed Central^® (PMC) database, the top 100 most-cited abstracts relevant to ADHD since 2014 were downloaded. Citation rank analysis was performed to compare the dominant roles of article types and topic categories using the pyramid plot. Social network analysis (SNA) was performed to highlight prominent entities for providing a quick look at the study result. The authors examined the MeSH prediction effect on article citations using its correlation coefficients (CC).

RESULTS

The most frequent article types and topic categories were research support by institutes (56%) and epidemiology (28%). The most productive countries were the United States (42%), followed by the United Kingdom (13%), Germany (9%), and the Netherlands (9%). Most articles were published in the Journal of the American Academy of Child and Adolescent Psychiatry (15%) and JAMA Psychiatry (9%). MeSH terms were evident in prediction power on the number of article citations (correlation coefficient = 0.39; t = 4.1; n = 94; 6 articles were excluded because they do not have MeSH terms).

CONCLUSIONS

The breakthrough was made by developing 1 dashboard to display 100 top-cited articles on ADHD. MeSH terms can be used in predicting article citations on ADHD. These visualizations of the top 100 most-cited articles could be applied to future academic pursuits and other academic disciplines.

Descriptive statistics was used to analyze the data. Pearson's correlation analysis was used to explore the relationships among Web of Science citations, Dimensions citations, and Altmetric Attention Score. The number of citations of an article in the top 100 most-cited papers published in 1953 or later ranged from 541 to 3623. The papers were published in 47 different journals. The New England Journal of Medicine, American Cancer Society, and Nature Genetics published the most papers. Authors from 18 different countries published papers on head and neck cancer, craniofacial congenital anomalies, and osteonecrosis. Most of the papers were laboratory and descriptive studies. A correlation analysis showed a strong correlation only between Web of Science and Dimensions citations. In sum, although non-specific journals for pathology and oral medicine published the majority of the 100 most-cited papers, this biometric citation study show that head and neck cancer was the issue with the most citations. Together, these results make an important scientific contribution by providing a historical perspective on the research carried out.

Bibliometric Analysis of Medication-Related Osteonecrosis of the Jaw: High Citation Rates but Low Evidence

PURPOSE

Citation analysis is one of the most commonly used bibliometric tools for measuring the academic importance of a report in a specific area of knowledge. The objective of the present study was to identify the 100 most cited reports on medication-related osteonecrosis of the jaw (MRONJ), determine their main bibliometric characteristics, and identify the bibliometric variables that affected the citation rates.

MATERIALS AND METHODS

We performed a data search in the Scopus database to determine the number of MRONJ article citations up to September 30, 2018. We next selected the 100 most referenced studies and recorded the following information: ranking according to the number of citations; citation density; number and names of authors; language and year of publication; country and institution of origin; financial support; journal name, impact factor, category, and quartile; type of research; evidence level; and area of study.

RESULTS

The 100 most cited reports had a mean citation density of 21.7 ± 20.7 (range, 6.2 to 99.4) and an h-index of 96. The 100 most cited reports on MRONJ had been published in 42 scientific journals, classified into 10 separate categories of the Journal Citation Reports; 56% of the articles were in the first quartile of their category. Most of the studies had been classified with a level of evidence of 4 (n = 45) or 5 (n = 29). In the bivariate analyses, only the conflict of interest (P = .002) was associated with citation density. After adjusting for numerous variables, conflict of interest (r = 0.27; P = .020) and country of the first author (r = 0.23; P = .043) were significantly associated with citation density.

CONCLUSIONS

The 100 most cited studies of MRONJ had a large number of citations and had been reported in journals with a high impact factor; however, the studies had a generally low evidence level and randomized clinical trials were lacking.

Prognostic role of platelet-to-lymphocyte ratio in oral cancer: A meta-analysis

BACKGROUND AND OBJECTIVE

Platelet-to-lymphocyte ratio (PLR) has been suggested to be associated with the progression of oral cancer with inconclusive results. The objective of the current study was to assess the prognostic role of oral cancer by meta-analysis.

METHOD

PubMed, EMbase(Ovid), CNKI, WanFang Data, VIP, and CBM databases were searched up to August 24, 2018. Studies investigating the association between PLR and progression of oral cancer were included. Meta-analysis was performed by using Revman 5.3 software. The protocol of the study was registered on PROSPERO (CRD42018106836).

RESULTS

A total of five studies were included in the meta-analysis. The results of the meta-analysis showed that higher PLR was associated with the poor progress of oral cancer (overall survival: OR = 2.06, 95 CI: 1.49-2.86, P < 0.0001; disease-specific survival: OR = 2.12, 95 CI: 1.59-2.82, P < 0.00001).

CONCLUSION

The current meta-analysis showed that higher PLR is a poor progression factor for oral cancer. However, larger sample, multi-center studies should be carried out in the future to validate the above conclusion.
