      OBJECTIVE: To describe how overly simple conceptualisations of how research is translated into public health policy impact impair effective translation. To suggest how alternative approaches to conceptualising impact, which incorporate recent developments in social and political sciences, can help stakeholders improve translation of high-quality public health research into policy impact.STUDY DESIGN: Researchers often describe generating impact in terms of linear or cyclical models, in which the production of scientific findings alone compels action and leads to impact. However, such conceptualisations do not appear to have supported improved translation of research into policy and practice. Improving understanding of how research impact is achieved may identify areas stakeholders seeking to achieve impact could target.
    METHODS: Overview of theoretical and practical approaches to achieving public health policy impact from research.
    RESULTS: Despite much evidence that translating research into public health policy is more complex than linear and cyclical models suggest, stakeholders often revert to these heuristics, that is shorthand ways of thinking that allow simple but inaccurate answers to complex problems. This leads to potentially missing opportunities for impact, such as conducting research in collaboration with local policy makers and contributing ideas to the wider narrative through the media and public engagement.
    CONCLUSION: The process of translating research into impact appears more complex than that suggested by linear and cyclical models. Success involves a planned approach targeting multiple routes to impact, sustained over time.

      BACKGROUND: Oral presentations at academic conferences typically describe recent or ongoing research projects or provide literature reviews. However, conversion of these presentations into full-length journal articles is not routine.OBJECTIVE: We sought to assess the frequency with which oral presentations at the Academy of Consultation-Liaison Psychiatry's annual meetings from 2012 to 2018 were turned into peer-reviewed publications and review the factors that affected publication of them.
    METHODS: Conference presentation titles and authors from the 2012-2018 Academy of Consultation-Liaison Psychiatry Annual Meetings were searched using PubMed to find corresponding published reports by the presenters. Data were organized in an Excel spreadsheet, and the time to publication, the journals in which they were published, and general content areas were recorded and analyzed.
    RESULTS: Of the 287 oral presentations delivered during the study period, 47% were published in a peer-reviewed journal. Articles were published in 72 different journals; the journals that published the most articles were Psychosomatics, General Hospital Psychiatry, Psycho-oncology, Academic Psychiatry, and the Journal of General Internal Medicine. The most common subspecialty topics of the published articles were neuropsychiatry, psycho-oncology, surgery and transplantation, and delirium. The mean time to publication after presentation was 1 year.
    CONCLUSION: Knowledge of the rate at which presentations are converted into peer-reviewed publications can be used to enhance the academic success of presenters, and strategies to enhance the rate of publication (e.g., by coaching on scientific writing or by selecting oral presentations with the highest publication potential) can be established.

      Despite efforts to promote diversity in the biomedical workforce, there remains a lower rate of funding of National Institutes of Health R01 applications submitted by African-American/black (AA/B) scientists relative to white scientists. To identify underlying causes of this funding gap, we analyzed six stages of the application process from 2011 to 2015 and found that disparate outcomes arise at three of the six: decision to discuss, impact score assignment, and a previously unstudied stage, topic choice. Notably, AA/B applicants tend to propose research on topics with lower award rates. These topics include research at the community and population level, as opposed to more fundamental and mechanistic investigations; the latter tend to have higher award rates. Topic choice alone accounts for over 20% of the funding gap after controlling for multiple variables, including the applicant's prior achievements. Our findings can be used to inform interventions designed to close the funding gap.

      Background: The effects of publishing case reports on journal impact factor and their impact on future research in pediatric dentistry has not been clearly evaluated yet. Aim. To assess the relevance and role of case reports in pediatric dentistry. Methods: A systematic review (PROSPERO registration number: CRD42018108621) of all case reports published between 2011 and 2012 in the three major pediatric dentistry journals was performed manually. Data regarding citations of each report were acquired from the Institute for Scientific Information database available online. The authors analyzed information regarding citations (number, percentage, and mean) received by each case report and considered their relation with the 2013 journal impact factor. Results: Case reports accounted for almost sixteen per cent of all articles published between 2011 and 2012. The citation rate of case reports was generally low and the highest mean citation was 0.5. This review revealed that 6 (9.52%) case reports had at least 5 citations and that the majority of the citing articles were also case reports (27.78%) or narrative reviews (25%). Conclusions: The publication of case reports affected the journal impact factor in a negative way, this influence is closely related to the percentage of the published case reports. Case reports about innovative topics, describing rare diseases, syndromes, and pathologies were more frequently cited.

      The Emerging Sources Citation Index and the internationalization of Spanish scientific journals, with special reference to Psychology journals.BACKGROUND: Spain is among the countries that have added more scientific journals into the Emerging Sources Citation Index (ESCI), a new product from the Central Collection of Web of Science. The aim of this paper is to analyze the implications of this and quantify the effects on Impact Factors.
    METHOD: The Spanish presence was quantified using the Master Journal List, converted to a spreadsheet for data processing. The implications were determined by analyzing the criteria "Journal Selection Process". The effect on impact factors was analyzed through a case study of Spanish JCR journals of Psychology.
    RESULTS: Until 2015, Spain represented 1.13% of the Central Collection. With the 568 journals included in the ESCI, that presence has increased to 3.37%. The areas benefitting most were Social Sciences and Humanities. As a general effect, citation in Psychology journals has increased by an average of 13.18%.
    CONCLUSIONS: The situation fostered by the ESCI will significantly improve the number and position of Spanish journals with impact factors in the short and medium term. Currently, their citations have already significantly influenced an increase of the impact of Spanish journals included in the Journal Citation Reports.

      Objective: To evaluate and compare the reporting of consolidated standard of reporting trial (CONSORT) flow diagrams in randomized controlled trials (RCTs) published in a national and international pharmacology journal.Methods: RCTs in an international pharmacology journal, European Journal of Clinical Pharmacology (EJCP), and a national journal, Indian Journal of Pharmacology (IJP), published from January 2014 to July 2016 were evaluated for reporting and completeness of CONSORT flow diagrams. A total of 138 articles (EJCP = 90; IJP = 48) were analyzed and compared.
    Results: Of 138 RCTs analyzed, 90 were from EJCP and 48 were from IJP. 76.6% (69/90) articles from EJCP and 37.5% (18/48) articles from IJP had reported the CONSORT flow diagram. Of these, 95.5% (66/69) had assessed for eligibility in EJCP and 88.8% (16/18) had reported the same in IJP. The number of participants excluded was reported in 86.9% (60/69) flow diagrams in EJCP and 83.3% (15/18) in IJP. 82.6% (57/69) flow diagrams in EJCP and 77.7% (14/18) in IJP had mentioned the details of randomization. Allocation of intervention was reported in 91.3% (63/69) flow diagrams in EJCP and 88.8% (16/18) in IJP. 60.8% (42/69) flow diagrams in EJCP and 44.4% (08/18) in IJP had mentioned the details of follow-up of participants. 95.5% (66/69) flow diagrams in EJCP and 94.4% (17/18) in IJP had mentioned details about analysis.
    Conclusion: In spite of both the journals, IJP and EJCP endorsing the CONSORT statement, a significant difference in the reporting of CONSORT flow diagrams in RCTs can be noted. The quality of reporting can be improved by stringent publication guidelines by the editors.

      The International Associations for Dental Research (IADR) annual meeting is one of the most important dental meetings throughout the world, and researches about paediatric dentistry presented in this platform are often used to guide clinical work. To evaluate the publication outcomes of oral and poster paediatric proceedings which were accepted by the International Associations for Dental Research (IADR) annual meetings from 2010 to 2016 and to analyze the possible factors influencing an abstract's progression to publication. Oral and poster abstracts were retrieved from the official website of IADR (2010-2016). Searching for subsequent publications was conducted in Pubmed and Google Scholar (up to March 2019). Two authors independently selected studies, collected and analyzed data. A total of 1396 abstracts were identified, including 275 oral presentations and 1121 poster presentations. Finally, 606 were published in peer-reviewed journals, with a publication rate of 43.41%. Abstracts were published earlier if it is from Europe, well funded, presented orally or with large sample size. The high publication rate of the IADR proceedings supported the impact of IADR annual meetings on paediatric dentistry in the last 10 years.

      Background: Generalists who pursue research-intensive fellowships develop research skills and mentor-mentee relationships. Whether gender disparities in retention and promotion exist among this research-trained cohort is understudied.Objective: We measured whether disparities exist among graduates of research-intensive fellowships and how mentorship influences them.
    Methods: We surveyed generalists (internal medicine, pediatrics, family medicine, combined internal medicine-pediatrics) between July and August 2016 who graduated from research-intensive fellowships. Generalists ("mentees") were asked whether they remained or were promoted, and to name up to 10 influential mentors during or within 5 years of fellowship. Multivariable logistic regression estimated associations between mentee gender and retention and promotion. Next, we separately included 3 network characteristics: (1) mentee degrees (number of mentors reported per mentee); (2) mean mentor betweenness centrality (importance of each mentor within the network); and (3) largest community membership (mentee status in the largest interconnected mentor-mentee group within the network). All models adjusted for generalists' race, specialty, fellowship institution, and publications.
    Results: One hundred sixty-two graduates (51%) representing 19 institutions responded. In adjusted analyses, compared to men, women were as likely to remain in academic medicine (odds ratio [OR] 1.88; 95% confidence interval [CI] 0.72-4.89; P = .20), but less likely to be promoted within 5 years of fellowship (OR 0.26; 95% CI 0.09-0.80; P = .018). Inclusion of network measures did not alter these associations.
    Conclusions: Despite remaining in academic medicine as frequently as their male counterparts, fellowship-trained women were promoted less often. Features of mentors, measured using network analysis, may not explain these observed differences.

      INTRODUCTION: Bibliometric analysis is being used more and more in orthopedics and traumatology. However, the quantity and quality of publications authored by French orthopedic and trauma surgeons outside their discipline have never been analyzed, nor has the change in the quality of orthopedics publications. This led us to carry out a bibliometric analysis to answer the following questions: 1) How has the quantity of scientific production by French orthopedists changed over the past 10 years? 2) How has the quality of the overall scientific production by French orthopedists changed over the past 10 years?HYPOTHESIS: From 2008 to 2017, the production of French orthopedists has increased in quantity and quality in orthopedics and other medical fields.
    MATERIAL AND METHODS: The analysis was performed by cross-referencing the list of SOFCOT (French Society for Orthopaedic Surgery and Traumatology) members with the French SIGAPS database and the InCites platform. Out of 3979 SOFCOT members, 972 (24%) had authored publications during this period and were included in the analysis. Several indicators were analyzed: number of publications; SIGAPS score (production quality) for the various Web of Science (WoS) categories; number and percentage of publications in the top 1% and top 10% (most highly cited articles worldwide).
    RESULTS: The "Orthopedics" discipline was still the most prevalent with 68% of all publications identified. The "Surgery" discipline was stable, and the share of publications had increased in five other disciplines: Sports Sciences, Clinical Neurology, Emergency Medicine, Engineering-Biomedical and Material Science-Biomaterials. Of the 727 journals indexed in PubMed in which at least one author is a French orthopedic or trauma surgeon, 79 journals (11%) had at least 10 articles authored by a French orthopedists, making up 4680/6056 published articles (77%) during the study period. The highest SIGAPS score was in the "Orthopedics" discipline followed by "Surgery", and then by "Sport Sciences" with a large number of publications in the SIGAPS B category. Publications in "Orthopedics" category A and B journals increased 14% during this period. When all disciplines are pooled, the share of publications in SIGAPS A, B and C categories increased by 10% from 2008 to 2017. The largest increase in publications for categories A and B and the top 1% and 10% was in "Sports Sciences".
    DISCUSSION: Over the past 10 years, French orthopedists have continued to increase their scientific production in the orthopedics field and in related fields such as Sport Sciences, Clinical Neurology and Biomedical Engineering. The quality of the scientific production of French orthopedists in their discipline and outside of it has greatly improved, as evidenced by the shift toward SIGAPS A and B journals.

      Research Ranking of Spanish Public Universities (2019).BACKGROUND: The changes produced in the Spanish university system due to the Bologna process require periodically updated evaluation reports of research activity. The objective of this study is to update the last available ranking of Spanish public universities, based on data from 2013-2018.
    METHOD: The production and productivity of each university were assessed based on seven specific indicators and a global score: articles in journals indexed in the JCR (Journal Citation Reports), research periods, R+D projects, doctoral theses, FPU (training of university professors) grants, FPI (training of personal researchers) grants, and patents.
    RESULTS: Globally, the universities Complutense of Madrid, Barcelona, and Granada hold the first positions in terms of production, while the first positions in terms of productivity are held by the universities Pompeu Fabra, Autonomous of Madrid, and Autonomous of Barcelona.
    CONCLUSIONS: The universities that hold the top positions in this ranking remain relatively steady over time and are also the Spanish universities that stand out in international classifications.

      BACKGROUND: Many authors are concerned which types of peer-review articles can be cited most in academics and who were the highest-cited authors in a scientific discipline. The prerequisites are determined by: (1) classifying article types; and (2) quantifying co-author contributions. We aimed to apply Medical Subject Headings (MeSH) with social network analysis (SNA) and an authorship-weighted scheme (AWS) to meet the prerequisites above and then demonstrate the applications for scholars.METHODS: By searching the PubMed database (pubmed.com), we used the keyword "Medicine" [journal] and downloaded 5,636 articles published from 2012 to 2016. A total number of 9,758 were cited in Pubmed Central (PMC). Ten MeSH terms were separated to represent the journal types of clusters using SNA to compare the difference in bibliometric indices, that is, h, g, and x as well as author impact factor(AIF). The methods of Kendall coefficient of concordance (W) and one-way ANOVA were performed to verify the internal consistency of indices and the difference across MeSH clusters. Visual representations with dashboards were shown on Google Maps.
    RESULTS: We found that Kendall W is 0.97 (χ = 26.22, df = 9, P < .001) congruent with internal consistency on metrics across MeSH clusters. Both article types of methods and therapeutic use show higher frequencies than other 8 counterparts. The author Klaus Lechner (Austria) earns the highest research achievement(the mean of core articles on g = Ag = 15.35, AIF = 21, x = 3.92, h = 1) with one paper (PMID: 22732949, 2012), which was cited 23 times in 2017 and the preceding 5 years.
    CONCLUSION: Publishing article type with study methodology and design might lead to a higher IF. Both classifying article types and quantifying co-author contributions can be accommodated to other scientific disciplines. As such, which type of articles and who contributes most to a specific journal can be evaluated in the future.

      OBJECTIVE: to analyze scientific evidence available in health literature on ethics, standardization and biometric indicators.METHOD: an integrative review carried out in August 2016, on the databases: National Library of Medicine, Literatura Latino-Americana e do Caribe em Ciências da Saúde (Latin-American and Caribbean Literature on Health Sciences), and on the library Scientific Electronic Library Online. The review included primary articles on: ethics, standardization and biometric indicators, in Portuguese, English, or Spanish; and excluded studies that were not found as full texts, as well as opinions, commentary, reviews, theses, and dissertations. For the evaluation of the articles, it was used evidence levels from one to five.
    RESULTS: eight articles were included, with scientific evidence levels 4 and 5: scientific productivism, production evaluation systems, internationalization, impact factor, classification of journals, and adequate and inadequate practices for publication.
    CONCLUSION: it was verified the need for publications with higher evidence levels so that Brazilian journals can follow international standards dealing with research ethics.

      PURPOSE: To investigate the quantity and quality of articles in the field of full-endoscopic spine surgery (FESS) from different countries and assess characteristics of worldwide research productivity.METHODS: Articles published from 1997 to July 23, 2018, were screened using the Web of Science database. All studies were assessed for the following parameters: the number of total publications, h-index, contribution of countries, authors, journals, and institutions.
    RESULTS: A total of 408 articles were identified between 1997 and 2018. Between 1997 and 2017, the number of published articles tended to increase by 41 times. The largest number of articles was from China (30.15%), followed by South Korea (28.68%), the USA (13.97%), Germany (9.31%), and Japan (4.90%). The highest h-index was found for articles from South Korea (23), followed by the USA (18), Germany (16), China (11), and Japan (7). The highest number of articles was published in World Neurosurgery (12.50%), followed by Pain Physician (10.29%), Spine (6.62%), European Spine Journal (4.66%), and Journal of Neurosurgery: Spine (4.17%). Wooridul Spine Hospital published the largest number of articles (10.29%), followed by Tongji University (5.88%), University of Witten/Herdecke (5.39%), Brown University (5.15%), and Third Military Medical University (3.43%).
    CONCLUSIONS: The number of articles published in the field of FESS has increased rapidly in the past 20 years. In terms of quantity, China is the most contributive country based on the number of publications. High-quality papers as measured by h-index and the large quantity is from South Korea (second only to China). These slides can be retrieved under Electronic Supplementary Material.

      Importance: In peer-reviewed medical journals, authoring an invited commentary on an original article is a recognition of expertise. It has been documented that women author fewer invited publications than men do. However, it is unknown whether this disparity is due to gender differences in characteristics that are associated with invitations, such as field of expertise, seniority, and scientific output.Objective: To estimate the odds ratio (OR) of authoring an invited commentary for women compared with men who had similar expertise, seniority, and publication metrics.
    Design, Setting, and Participants: This matched case-control study included all medical invited commentaries published from January 1, 2013, through December 31, 2017, in English-language medical journals and multidisciplinary journals. Invited commentaries were defined as publications that cite another publication within the same journal volume and issue. Bibliometric data were obtained from Scopus. Cases were defined as corresponding authors of invited commentaries in a given journal during the study period. Controls were matched to cases based on scientific expertise by calculating a similarity index for abstracts published during the same period using natural language processing. Data analyses were conducted from March 13, 2019, through May 3, 2019.
    Exposure: Corresponding or sole author gender was predicted from author first name and country of origin using genderize.io.
    Main Outcomes and Measures: The OR for gender was estimated after adjusting for field of expertise, publication output, citation impact, and years active (ie, years since first publication), with an interaction between gender and years active.
    Results: The final data set included 43 235 cases across 2549 journals; there were 34 047 unique intraciting commentary authors, among whom 9072 (26.6%) were women. For researchers who had been active for the median of 19 years, the odds of invited commentary authorship were 21% lower for women (OR, 0.79 [95% CI, 0.77-0.81]; P < .001) compared with men who had similar scientific expertise, number of publications, and citation impact. For every decile increase in years active, the OR decreased by a factor of 0.97 (95% CI, 0.96-0.98; P < .001).
    Conclusions and Relevance: In this case-control study, women had lower odds of authoring invited commentaries than their male peers. This disparity was larger for senior researchers. Journal editors could use natural language processing of published research to widen and diversify the pool of experts considered for commentary invitations.

      Social networks have historically been used to share information and support regarding health-related topics, and this usage has increased with the rise of online social media. Young people are high users of social media, both as passive listeners and as active contributors. This study aimed to map the trends in publications focused on social networks, health, and young people over the last 40 years. Scopus and the program VOSviewer were used to map the frequency of the publications, keywords, and clusters of researchers active in the field internationally. A structured keyword search using the Scopus database yielded 11,966 publications. The results reveal a long history of research on social networks, health, and young people. Research articles were the most common type of publication (68%), most of which described quantitative studies (82%). The main discipline represented in this literature was medicine, with 6062 documents. North American researchers dominate the field, both as authors and partners in international research collaborations. The present article adds to the literature by elucidating the growing importance of social networks in health research as a topic of study. This may help to inform future investments in public health research and surveillance using these novel data sources.

      In this study, we characterize the body of knowledge of groundwater remediation from 1950 to 2018 by employing scientometric techniques and CiteSpace software, based on the Science Citation Index Expanded (SCI-E) databases. The results indicate that the United States and China contributed 56.4% of the total publications and were the major powers in groundwater remediation research. In addition, the United States, Canada, and China have considerable capabilities and expertise in groundwater remediation research. Groundwater remediation research is a multidisciplinary field, covering water resources, environmental sciences and ecology, environmental sciences, and engineering, among other fields. Journals such as Environmental Science and Technology, Journal of Contaminant Hydrology, and Water Research were the major sources of cited works. The research fronts of groundwater remediation were transitioning from the pump-and-treat method to permeable reactive barriers and nanoscale zero‑valent iron particles. The combination of new persulfate ion‑activation technology and nanotechnology is receiving much attention. Based on the visualized networks, the intelligence base was verified using a variety of metrics. Through landscape portrayal and developmental trajectory identification of groundwater remediation research, this study provides insight into the characteristics of, and global trends in, groundwater remediation, which will facilitate the identification of future research directions.

      Background: Sialadenoma papilliferum is a benign rare condition of salivary glands showing a characteristic papillary growth of the ductal epithelium that ends up being confused with more frequent lesions of the oral cavity. Objectives: To perform a bibliometric analysis of all articles about Sialadenoma papilliferum in the oral cavity and to add a singular case report of Sialadenoma in the lower lip.Material and Methods: A total of 36 publications referring to Sialadenoma papilliferum in the oral cavity from the PubMed platform was reviewed. The specific data were collected, and a bibliometric analysis was performed using Microsoft Excel. The results obtained were then compared with this new case report.
    Results: The people most affected with sialadenoma were white males at the average age of 56. The lesion was asymptomatic, usually white or red, with an average size of 1.4 cm, and the palate was by far the most affected site. The majority of the lesions were excised, and only two cases indicated recurrence.
    Conclusions: With surgical removal, Sialadenoma papilliferum has a favorable prognosis and no further treatment is required. Due to few recorded cases of recurrence, a long follow-up period is recommended to ensure that the lesion does not redevelop. Key words:Sialadenoma papilliferum, salivary gland, oral cavity, bibliometric analysis.

      The introduction of antiretroviral therapy (ART) has helped HIV population to live longer, but they could face not only AIDS-related morbidity but also other non-communicable diseases. Paying attention to ART adherence requires a system thinking with the life-long factors, individual-environment interactions and contextualized dynamics. Although several quantitative research had been conducted, they were not able to fully demonstrate the development of research approaches and scopes of previous studies. Essential and practical public health policy should be based on the most accessible and strategically analyzed evidence. Therefore, our study uses a scientometric approach to supplement previous reviews research covering until the end of 2017. Using a combination of two quantitative approaches to supplement previous reviews, we attempt to identify the research trends and potential research gaps which could be very helpful for policies and practices enhancements to inform evidence-based strategies. Our result indicates countries tend to collaborate in traditional models rather than prioritize severity and characteristics of HIV epidemics. Further ART research should highlight the incorporation of newly developed technology to examine long-term impacts, combine multiple measures, address contextual factors, and involve available technologies and resources, e.g., family, community.

      BACKGROUND: Most glioma patients experience recurrence and have a poor prognosis. Scientometric analysis is effective and widely used to summarize the most influential studies within a certain field. We present the first scientometric analysis of recurrent glioma.METHODS: We conducted a generalized search for articles on recurrent glioma in the Web of Science database and evaluated the top 100 most cited articles among a total of 4,651 articles.
    RESULTS: The number of citations from the top 100 cited articles on recurrent glioma ranged from 149 to 1,471; the majority of these articles were published in oncology-specific journals (66) and were submitted by institutions in the United States of America (67). The top-cited articles consisted of 98 articles and 2 literature reviews. Articles were classified into 4 major categories based on subject matter: 82 pertained to treatment, 6 pertained to genetic mechanisms, 7 pertained to diagnosis, and 5 pertained to prognosis. Treatment-related articles were subdivided into the following 7 categories: targeted therapy (21), chemotherapy (20), immunotherapy (12), combination therapy (12), radiotherapy (9), surgical resection (6), a new therapy (physiotherapy) (1), and treatment summary (1).
    CONCLUSIONS: The results of the analysis indicated that the core problem is the treatment of recurrent glioma. Although the number of citations on targeted therapy and combination therapy has increased in recent years, the proportion of randomized controlled trials (RCTs), basic medical research, literature reviews and meta-analyses is relatively low; thus, there is an urgent need to conduct these types of studies on recurrent glioma.

      So far, no Chinese- or English-language journal investigations have been carried out on the entirety of research published on intimate partner violence (IPV) in China. Accordingly, the main purpose of this study was to analyze the contents of the totality of published IPV research articles indexed in China National Knowledge Infrastructure (CNKI). Specifically, the study aimed to investigate the input and output factors relating to published articles concerned with IPV, including their authors and contents. The CNKI was selected for investigation and analysis because it is the largest and most consulted academic online library in China. The analysis was conducted on 3,595 peer-reviewed journal articles on IPV over a 37-year period covering 1982-2018. The findings revealed that only 68 (1.89%) of the articles were empirically and quantitatively based. Findings among these 68 articles show that total contribution of IPV research has increased significantly over time in China, with increasing growth in the past two decades especially. Results also present summaries concerned with the reviewed studies' inputs (i.e., researchers' organizational affiliations, funding sources, and geographic settings), outputs (i.e., authors, journals, classifications, pages, topics, key words, definitions, theoretical approaches, samples, and methods), and outcomes (i.e., citations, downloads, prevalence rates, and correlates of violence). To sum, this is the first exploratory study of the unique and diverse body of IPV research in the Chinese-language and scientific literature. Overall, the study's results both help to inform future IPV research in China and foster and inform communications concerning IPV research globally.
