The 100 most cited manuscripts in emergency abdominal surgery: A bibliometric analysis

Gender disparities in high-quality dermatology research over the past 15 years

Background

In the last 15 years, an increase in U.S. female dermatologists from 41 to 52.2% and a surge in female authorship (FAP) have been noted. Authorship is a pivotal objective measurement of academic productivity and, contribution as first or senior author, plays a major role in the promotion process of active physicians and faculty members.

Objective

To validate, analyze, and clarify trends in FAP in high-quality dermatology research in the last 15 years.

Methods

The Thomson Reuters Web of Science Journal Citation Reports 2021 was used to retrieve the 100 most-cited original articles from the top 5 dermatology journals (determined by 2021 impact factors) in 5 consecutive 3-year intervals between 2009 and 2023. Gender application programming interface, a gender algorithm, was used to identify FAP according to country of origin and first name. Monotonic trend test significance level was set at 5%.

Results

In total, 14,187 articles were retrieved and subdivided into the 100 most-cited in 3-year intervals. A total of 418 first and 447 senior authors' gender were identified. FAP was found in 43%, 31%, and 37% of the first, last, and total authors. Trend analysis revealed a decrease in the last 15 years (S = -4610, P = .068) in senior FAP. Similarly, the trend persists in the United States (S = -1606, P = .052).

Limitations

Due to the usage of a binary gender identification algorithm, Nonbinary gender could not be identified in this analysis.

Conclusion

The last 15 years show an inverse relationship, with an increase in female dermatologists and a decrease in senior FAP in high-quality journals in the general dermatology community.

The 100 most-cited manuscripts in epilepsy epigenetics: a bibliometric analysis

PURPOSE

The top citation article reflects the developmental milestone of a given field. The purpose of this bibliometric analysis was to identify and assess the 100 most-cited (T100) articles on the epigenetics mechanism of epilepsy.

METHODS

The Web of Science Core Collection (WoSCC) database was used to investigate, and search terms related to epilepsy epigenetics were compiled. Results were ranked according to citation number. The publication year, citation density, authorship, journal, country, institution, manuscript type, theme, and clinical topics were further evaluated.

RESULTS

The Web of Science search returned a total of 1231 manuscripts. The number of citations for a manuscript ranges from 739 to 75. The greatest number of manuscripts in the top 100 was published in the Human Molecular Genetics and Neurobiology of Disease (n = 4). The journal with the highest 2021 impact factor was Nature Medicine (IF = 87.244). The most-cited paper by Aid et al. reported a new nomenclature for mouse and rat BDNF gene and its expression profiles. Most manuscripts were original articles (n = 69), of which 52 (75.4%) report findings of basic scientific work. The most prevalent theme was microRNA (n = 29), and the most popular clinical topic was temporal lobe epilepsy (n = 13).

CONCLUSIONS

The research on the epigenetics mechanism of epilepsy was in its infancy but full of potential. The developmental history and current achievements of hot themes, including microRNA, DNA methylation, and temporal lobe epilepsy, were overviewed. This bibliometric analysis provides useful information and insight for researchers when launching new projects.

Out-of-hospital cardiac arrest: A data-driven visualization of collaboration, frontier identification, and future trends

One of the main causes of death is out-of-hospital cardiac arrest (OHCA), which has a poor prognosis and poor neurological outcomes. This phenomenon has attracted increasing attention. However, there is still no published bibliometric analysis of OHCA. This bibliometric analysis of publications on OHCA aimed to visualize the current status of research, determine the frontiers of research, and identify future trends. Publications on OHCA were downloaded from the web of science database. The data elements included year, countries/territories, institutions, authors, journals, research areas, citations of publications, etc. Joinpoint regression and exponential models were used to identify and predict the trend of publications, respectively. Knowledge domain maps were applied to conduct contribution and collaboration, cooccurrence, cocitation, and coupled analyses. Timeline and burst detection analysis were used to identify the frontiers in the field. A total of 3 219 publications on OHCA were found from 1998 to 2022 (average annual percentage change = 16.7; 95% CI 14.4, 19.1). It was estimated that 859 articles and reviews would be published in 2025. The following research hotpots were identified: statement, epidemiology, clinical care, factors influencing prognosis and emergency medical services. The research frontier identification revealed that 7 categories were classified, including therapeutic hypothermia, emergency medical services, airway management, myocardial infarction, extracorporeal cardiopulmonary resuscitation, stroke foundation and trial. The burst detection analysis revealed that percutaneous coronary intervention, neurologic outcome, COVID-19 and extracorporeal cardiopulmonary resuscitation are issues that should be given continual attention in the future. This bibliometric analysis may reflect the current status and future frontiers of OHCA research.

The 100 Most-Cited Manuscripts in Hearing Implants: A Bibliometrics Analysis

The aim of the study was to characterise the most frequently cited articles on the topic of hearing implants. A systematic search was carried out using the Thomson Reuters Web of Science Core Collection database. Eligibility criteria restricted the results to primary studies and reviews published from 1970 to 2022 in English dealing primarily with hearing implants. Data including the authors, year of publication, journal, country of origin, number of citations and average number of citations per year were extracted, as well as the impact factors and five-year impact factor of journals publishing the articles. The top 100 papers were published across 23 journals and were cited 23,139 times. The most-cited and influential article describes the first use of the continuous interleaved sampling (CIS) strategy utilised in all modern cochlear implants. More than half of the studies on the list were produced by authors from the United States, and the Ear and Hearing journal had both the greatest number of articles and the greatest number of total citations. To conclude, this research serves as a guide to the most influential articles on the topic of hearing implants, although bibliometric analyses mainly focus on citations. The most-cited article was an influential description of CIS.

Minimally-invasive cardiac surgery: a bibliometric analysis of impact and force to identify key and facilitating advanced training

Background

The number of citations an article receives is a marker of its scientific influence within a particular specialty. This bibliometric analysis intended to recognise the top 100 cited articles in minimally-invasive cardiac surgery, to determine the fundamental subject areas that have borne considerable influence upon clinical practice and academic knowledge whilst also considering bibliometric scope. This is increasingly relevant in a continually advancing specialty and one where minimally-invasive cardiac procedures have the potential for huge benefits to patient outcomes.

Methods

The Web of Science (Clarivate Analytics) data citation index database was searched with the following terms: [Minimal* AND Invasive* AND Card* AND Surg*]. Results were limited to full text English language manuscripts and ranked by citation number. Further analysis of the top 100 cited articles was carried out according to subject, author, publication year, journal, institution and country of origin.

Results

A total of 4716 eligible manuscripts were retrieved. Of the top 100 papers, the median (range) citation number was 101 (51–414). The most cited paper by Lichtenstein et al. (Circulation 114(6):591–596, 2006) published in Circulation with 414 citations focused on transapical transcatheter aortic valve implantation as a viable alternative to aortic valve replacement with cardiopulmonary bypass in selected patients with aortic stenosis. The Annals of Thoracic Surgery published the most papers and received the most citations (n = 35; 3036 citations). The United States of America had the most publications and citations (n = 52; 5303 citations), followed by Germany (n = 27; 2598 citations). Harvard Medical School, Boston, Massachusetts, published the most papers of all institutions. Minimally-invasive cardiac surgery pertaining to valve surgery (n = 42) and coronary artery bypass surgery (n = 30) were the two most frequent topics by a large margin.

Conclusions

This work establishes a comprehensive and informative analysis of the most influential publications in minimally-invasive cardiac surgery and outlines what constitutes a citable article. Undertaking a quantitative evaluation of the top 100 papers aids in recognising the contributions of key authors and institutions as well as guiding future efforts in this field to continually improve the quality of care offered to complex cardiac patients.

Recent Publication Trends in Radiotherapy and Male Infertility over Two Decades: A Scientometric Analysis

Radiotherapy, a popular cancer management procedure, negatively impacts reproductive health particularly by reducing the fertility potential. The purpose of this study was to analyze the research trend in radiotherapy associated with male infertility over the past 20 years (2000-May 2021). SCOPUS database was used to retrieve relevant scientometric data (publication per year, affiliation, journals, countries, type of document and area of research) for different subgenres of radiotherapy and male infertility. A total of 275 articles were published related to radiotherapy and male infertility, with the United States being the most dominant country in research output in this field. Radiotherapy and male infertility research have shown positive growth over the last two decades. In-depth analysis revealed that publications (n) related to radiotherapy and male infertility research mainly focused its impact on semen parameters (n = 155) and fertility preservation techniques (n = 169). Our scientometric results highlight a limited research focus on the field of radiotherapy and its impact on male reproductive hormones. Furthermore, a significant lack of research was noticed in the area of omics and male reproductive organs linked to radiotherapy. Substantial research is warranted to further decipher the effect of radiotherapy, at molecular level, leading to male infertility.

50 years in urinary incontinence: a bibliometric analysis of the top 100 cited articles of the last 50 years

INTRODUCTION

A large body of literature has been published on urinary incontinence, ranging from medical treatment, epidemiology and surgical techniques. A bibliometric analysis is used to identify high-quality research papers using criteria such as citation rate and journal impact factor.

OBJECTIVES

To describe key themes and topics in urinary incontinence literature in the last 50 years.

METHODS

Thomson Reuters Web of Science citation indexing database was used to identify the top 100 cited articles in urinary incontinence in the last 50 years. Data sets were subdivided into manuscript type, theme, author, institution, country of origin, journal and citation rate.

RESULTS

Mean number of citations in the top 100 group for manuscripts was 676, ranging between 2444 and 306. Most cited paper was by Irwin et al. The manuscript with the highest citation rate was by Dumoulin et al., citation rate of 470.7/year. The largest number of manuscripts was published between 2000 and 2009 (n = 47). The New England Journal of Medicine (NEJM) had the highest impact factor (74.67) and five manuscripts were published in this journal. Fifty-seven per cent of articles were published in journals with impact factor < 5. The vast majority of the articles focussed on epidemiology, followed by surgical treatment of urinary incontinence, 69% being original research studies.

CONCLUSION

This is the first bibliometric analysis of the top 100 most influential papers in urinary incontinence. The key themes identified were epidemiology and surgical management, with most papers being original research studies.

The 100 Most Mentioned Glaucoma Articles Online With Highest Altmetric Attention Scores

PRCIS

Characteristics of the most mentioned glaucoma articles on the internet were analyzed, allowing a better understanding of the dissemination of glaucoma research to the general public.

PURPOSE

The aim was to determine the 100 most mentioned articles on the internet in the field of glaucoma and analyze their characteristics.

MATERIALS AND METHODS

We identified the top 100 glaucoma articles with the highest Altmetric Attention Score (AAS), an automatically calculated metric for monitoring social media. Each article was evaluated for several characteristics including year of publication, title, journal name, journal impact factor (IF), article topic, article type, affiliation, and online mentions (news, blog, policy, Twitter, Facebook, etc.). Correlation analysis was conducted for AAS with these characteristics.

RESULTS

The selected 100 articles came from 44 journals with more than half (56%) published in ophthalmology-specific journals. There was no significant correlation between IF and number of articles in a specific journal or AAS (P>0.1), but the number of articles in the top 100 was higher for ophthalmology journals with a higher IF (P<0.05). Original study was the most common study type (87%), of which clinical observation study was the most common subgroup (40%). Epidemiology/risk factor and basic science were the most common article topics (each 24%), followed by medical treatment (13%). Article topics regarding medical treatment had a significantly greater AAS than other topics (P<0.05). Of the top 5 articles, more than half (60%) were related to "Lifestyle choice" topics.

CONCLUSIONS

There was no association between journal IF and AAS, consistent with previous studies. 90% of journals that had articles in the top 100 had a Twitter page. "Lifestyle choice" activities and other modifiable risk factors attracted significant online attention regarding glaucoma studies, with two of the top three most mentioned articles related to dietary intake. The present study thus provides a better understanding of online engagement with glaucoma research and the dissemination of this research to the general public.

Top 100 most influential manuscripts in erectile dysfunction

Erectile dysfunction (ED) is a common condition encountered by an array of subspecialists and is the most cited research topic within the field of andrology. This bibliometric analysis aims to identify the most influential papers that inform current clinical practice and likely shape future research. The Thompson Reuters Web of Science citation database was interrogated using search terms to cover the breadth of erectile dysfunction. Results were ranked according to citation number with country of origin, journal, topic, year of publication, author and institution also analysed. The search criteria matched 12,570 manuscripts. The top 100 highest citation ranged from 3013 to 161 (median 229.5). The most cited manuscript reports the prevalence and risk factors of ED within the Massachusetts Male Aging Study. The most manuscripts were published by the Journal of Urology (n = 15) with a total of 7913 citations. Institutions from the USA contributed the majority (n = 55) with the UK (n = 14) second. The most common theme represented was epidemiology (n = 46) followed by treatment (n = 27). This analysis provides a list of the most influential manuscripts within ED and illustrates what can be considered a 'highly citable' paper. The most influential papers in Erectile Dysfunction remain seminal works from the end of the last century. The most cited manuscript has been cited 194 times in the last 17 months showing its continued value. Only one paper published within the last decade has reached the top twenty exemplifying the relative lack of novel influential publications.

Highly Cited Articles in the Field of Male Infertility and Antioxidants: A Scientometric Analysis

Purpose

The objective of this scientometric analysis was to recognize the top 100 cited articles on ‘Male infertility and Antioxidants’ and analyze its publication characteristics.

Materials and Methods

The Scopus database was used to retrieve related articles and the top 100 identified based on citation rate.

Results

The articles were published in 56 journals between 1995 and 2019 with a median (interquartile range) citation score of 17 (5–62).

In addition to conventional semen parameters, advanced sperm function tests such as oxidative stress (51%) and sperm DNA damage (23%) were reported. Pregnancy rate (33%) was found to be the most reported reproductive outcome. Antioxidant therapy was mostly investigated in male cohorts with sperm abnormalities such as asthenozoospermia (28%) and clinical conditions such as idiopathic male infertility (20%), varicocele/varicocelectomy (17%) and general male infertility (16%).

Conclusions

The most influential publications on antioxidants and male infertility were identified for the first time in the literature. This will serve as a reliable source of information for researchers and clinicians alike.

The top 100. Review of the most cited articles on pancreas and laparoscopy

INTRODUCTION

The number of citations is considered as an indirect indicator of the merit of an article, journal or researcher, although it is not an infallible method to determine scientific quality. Our goal is to determine the characteristics of the articles most cited about pancreas and laparoscopy.

METHODS

We performed a search of all articles published in any journal about pancreas and laparoscopy until September 2019 and selected the 100 most cited papers. We recorded number of citations, journal, year of publication, quartil, impact factor, institution, country, authors type of paper, type of surgery, topic and area.

RESULTS

The top 100 citations account 10,970 citations in total. The journal with the most articles is Surgical Endoscopy and 2007 is the year with the highest number of articles in the top 100 citations. The percentage of publications from America and Europe are similar. Case series is the most frequently paper, outcomes/morbidity is the most frequently discussed topic, and distal pancreatectomy is the most frequently type of surgery.

CONCLUSIONS

This bibliometric study on pancreas and laparoscopy is conditioned by the time factor, since laparoscopy has arrived later at pancreatic surgery, probably due to the morbidity and mortality associated with pancreatic surgery and the need for a high specialization in this field. The literature is recent and scarce. More and better-quality studies are needed in this field.

Descriptive bibliometric analysis of global publications in lifestyle-based preventive cardiology

BACKGROUND

Lifestyle-based preventive cardiology aims to combat the global burden of cardiovascular disease. There have been rapid advances in lifestyle and behavioural interventions aimed at preventing cardiovascular disease in individuals at high risk and in the general population. This study is the first bibliometric analysis of publications in the field of lifestyle-based preventive cardiology.

METHODS

Journal articles relating to lifestyle-based preventive cardiology published from 1996 to 2017 were retrieved from the Scopus database. The publications were limited to those in the English language. The data were indexed using bibliometric methodology and exported to Microsoft Excel for analysis. VOS viewer software was used to conduct co-occurrence and collaboration analysis between authors, institutions and countries.

RESULTS

A total of 3300 publications were identified. The annual growth rate of publications increased globally during the study period. The USA made the highest contribution to global publications (1402) and total citation counts (68,540). Harvard Medical School was the most prolific institution and David Wood was the most prolific author in the field. The European Journal of Preventive Cardiology published the largest number of articles in this field. Obesity was the most common theme.

CONCLUSIONS

The current growth trends predict a large increase in the number of global publications on lifestyle-based preventive cardiology. Further research could focus on smoking cessation, which at present is under-represented in lifestyle-based preventive cardiology output.

Bibliometric analyses allow us to identify the most influential work, and future research. We aim to highlight the key research themes within ECS and determine their potential impact on cardiothoracic training.

Methods

Thomas Reuters Web of Science was searched using terms [Emergency AND Card* AND Surg*]. Results were ranked by citation and reviewed by a panel of cardiac surgeons to identify the top 100 cited papers relevant to ECS. Papers were analysed by topic, journal and impact. Regression analysis was used to determine a link between impact factor and scientific impact.

Results

3823 papers were identified. Median citations for the top 100 was 88. The paper with the highest impact was by Nashef et al. focusing on the use of EuroSCORE (2043 citations). The Annals of Thoracic Surgery published most papers (n = 18:1778 citations). The European Journal of Cardiothoracic Surgery coveted the most citations (n = 2649). The USA published most papers (n = 55).The most ubiquitous topics were; risk stratification, circulatory support and aortic surgery. A positive relationship between journal impact fact and the scientific impact of manuscripts in ECS (P = 0.043) was deduced.

Conclusion

This study is the first of its kind and identified the papers which are likely to the contribute most to training and understanding of ECS. A papers influence is partially determined by journal impact factor. Bibliometric analysis is a potent tool to identify surgical training needs.

The 100 most cited articles in the endovascular treatment of thoracic and abdominal aortic aneurysms

OBJECTIVE

Since the introduction of endovascular technology to treat thoracic and abdominal aortic aneurysms, there has been a global research effort focused on assessing the effectiveness of treatment. A bibliometric analysis is used to identify the scientific impact of an article, impactful authors, institutions, and collaborative groups. Our objective was to identify and to analyze the 100 most cited articles in the field of endovascular treatment of thoracic and abdominal aortic aneurysms.

METHODS

We performed a retrospective bibliometric analysis in April 2018. Articles were searched on the Science Citation Index Expanded database using Web of Science to identify the most cited articles in endovascular therapy for thoracic and aortic aneurysms since 1945. Use of selected key terms ("AAA," "aortic aneurysm," "thoracic aneurysm," "abdominal aneurysm," "endovascular," "endoluminal," "stent," "graft," "repair," "EVAR," and "TEVAR") yielded a total of 23,354 articles. The top 100 articles were identified and analyzed to extract relevant information including year of publication, citation count, journal, authorship country of origin, and article type.

RESULTS

The earliest articles were published in 1991, with the majority being published in the 2000s (n = 59). The number of citations for the top 100 articles ranged from 151 to 1142, with a median citation count of 212. All articles were cited an average of 22.4 times per year. Almost half (n = 46) of the top 100 articles were published in the Journal of Vascular Surgery. Thirty-nine authors contributed four or more articles, with two being credited on 10 papers to make the list. The majority (n = 62) of the articles arose from the United States, while the United Kingdom contributed 11 articles. There were 7 guidelines and 12 randomized controlled trials, and the majority constituted level III or level IV evidence.

CONCLUSIONS

This study provides a comprehensive and informative analysis of the most cited and impactful research undertaken in the field of endovascular treatment of abdominal and thoracic aortic aneurysms. By quantitatively assessing the 100 most cited articles in the field, we recognize the contributions of key authors, institutions, and collaborative groups and develop an understanding of the strengths of past research and the requirements for future global efforts.

The top 100: A review of the most cited articles in Surgery

INTRODUCTION

We performed a study of the top 100 most cited articles in the five general surgery journals with the highest impact according to Journal Citation Report.

METHODS

We selected the five journals with the highest impact in 2015: Annals of Surgery, British Journal of Surgery, JAMA Surgery, Surgery, and Journal of the American College of Surgeons. In January 2017, using the Web of Science application, we performed a search of all articles published by these journals and identified the 100 most cited articles (top 100). We evaluated the number of citations, year of publication, type of article, country and hospital of the article, area of interest and number of authors.

RESULTS

The median number of citations per top 100 paper was 490. Twenty percent of the top 100 papers have been published since 2000. Overall, 70% are original papers, 8% randomized control trials, 11% reviews, 1% meta-analyses and 11% other subtypes. There are 13% proceedings papers. Sixty-one percent are from the US. The most frequently discussed topic is hepato-pancreato-biliary surgery (33%).

CONCLUSIONS

The top 100 most cited articles tend to be original articles describing studies carried out in the US, reporting significant surgical breakthroughs. Hepato-pancreato-biliary surgery is the most common subject area. Annals of Surgery had twice as many citations as the other journals studied. The archetypal article of the Top15 most cited is an original paper published in the twentieth century, with an average of 2000 citations.

The 100 most influential manuscripts in andrology: a bibliometric analysis

Background

As the specialty of Andrology expands it is important to establish the most important studies that have shaped, and continue to shape, current research and clinical practice. Bibliometric analysis involving a citation rank list is an established means by which to identify the published material within a given field that has greatest intellectual influence. This bibliometric analysis sought to identify the 100 most influential manuscripts in Andrology, as well as the key research themes that have shaped contemporary understanding and management of andrological conditions.

Methods

The Thompson Reuters Web of Science citation indexing database was interrogated using a number of search terms chosen to reflect the full spectrum of andrological practice. Results were ranked according to citation number and further analysed according to subject, first and senior author, journal, year of publication, institution and country of origin.

Results

The Web of Science search returned a total of 24,128 manuscripts. Citation number of the top 100 articles ranged from 2819 to 218 (median 320). The most cited manuscript (by Feldman et al., The Journal of Urology 1994; 2819 citations) reported the prevalence and risk factors for erectile dysfunction (ED) in the Massachusetts Male Ageing Study. The Journal of Urology published the highest number of manuscripts (n = 11), followed by the New England Journal of Medicine (n = 10). The most common theme represented within the top 100 manuscripts was erectile dysfunction (n = 46), followed jointly by hypogonadism and male factor infertility (n = 24 respectively).

Conclusion

Erectile dysfunction should be considered the most widely researched, published and cited field within andrological practice. This study provides a list of the most influential manuscripts in andrology and serves as a reference of what comprises a ‘highly citable’ paper for both researchers and clinicians.

Altmetric Versus Bibliometric Perspective Regarding Publication Impact and Force

BACKGROUND

Bibliometric and Altmetric analyses highlight key publications, which have been considered to be the most influential in their field. The hypothesis was that highly cited articles would correlate positively with levels of evidence and Altmetric scores (AS) and rank.

METHODS

Surgery as a search term was entered into Thomson Reuter's Web of Science database to identify all English-language full articles. The 100 most cited articles were analysed by topic, journal, author, year, institution, and AS.

RESULTS

By bibliometric criteria, eligible articles numbered 286,122 and the median (range) citation number was 574 (446-5746). The most cited article (Dindo et al.) classified surgical complications by severity score (5746 citations). Annals of Surgery published most articles and received most citations (26,457). The country and year with most publications were the USA (n = 50) and 1999 (n = 11). By Altmetric criteria, the article with the highest AS was by Bigelow et al. (AS = 53, hypothermia's role in cardiac surgery); Annals of Surgery published most articles, and the country and year with most publications were USA (n = 4) and 2007 (n = 3). Level-1-evidence articles numbered 13, but no correlation was found between evidence level and citation number (SCC 0.094, p = 0.352) or AS (SCC = 0.149, p = 0.244). Median AS was 0 (0-53), and in articles published after the year 2000, AS was associated with citation number (r = 0.461, p = 0.001) and citation rate index (r = 0.455, p = 0.002). AS was not associated with journal impact factor (r = 0.160, p = 0.118).

CONCLUSION

Bibliometric and Altmetric analyses provide important but different perspectives regarding article impact, which are unrelated to evidence level.

Global Tissue Engineering Trends: A Scientometric and Evolutive Study

Tissue engineering (TE) is defined as a multidisciplinary scientific discipline with the main objective to develop artificial bioengineered living tissues to regenerate damaged or lost tissues. Since its appearance in 1988, TE has globally spread to improve current therapeutic approaches, entailing a revolution in clinical practice. The aim of this study is to analyze global research trends on TE publications to realize the scenario of TE research from 1991 to 2016 by using document retrieval from Web of Science database and bibliometric analysis. Document type, language, source title, authorship, countries and filiation centers, and citation count were evaluated in 31,859 documents. Obtained results suggest a great multidisciplinary role of TE due to a wide spectrum-up to 51-of scientific research areas identified in the corpus of literature, being predominant technological disciplines as Material Sciences or Engineering, followed by biological and biomedical areas, as Cell Biology, Biotechnology, or Biochemistry. Distribution of authorship, journals, and countries revealed a clear imbalance, in which a minority is responsible for a majority of documents. Such imbalance is notorious in authorship, where a 0.3% of authors are involved in half of the whole production.
