“…[29] Recent attempts have been made to evaluate the performance of authors with the use of the Y-index [30] by using indicators related to both first author articles and corresponding author articles, including studies in the fields of medicine, [31] environmental science, [32] risk assessment, [33] desalination, [34] global climate change, [35] university comparisons, [36] country characteristics, [37] and emergency medicine. [38] The Y-index, including both first authorship and corresponding authorship, has also been applied to evaluate the top-cited research articles in the Science Citation Index Expanded (SCI-Expanded [39,40] ) and in the independent research of China. [41] The first research question aims to evaluate the Y-index (or enhanced Y-index called Yk-index) in relation to AIC/R for a specific journal.…”

“…The greater the value of j is, the greater the contribution of the corresponding and first (co-first) authors to the science community. [38] The first disadvantage of the Y-index is the J(=FP + RP) from 1 to false∝ instead of normalizing falsenormalj=RP2+FP2 to be a radius equal to 1.0 based on the maximal j in Equation (2). Therefore, the Yk-index was proposed to enhance the Y-index.…”

Background: A consensus exists that the first author and corresponding author make the most contribution to the publication of an article. The Y-index has been proposed to assess the scientific achievements of authors, institutions, and countries/regions (AIC/R for short) based on the number of first-author publications (FPs) and corresponding-author publications (RPs). Nonetheless, the Y-index is defined in terms of count and radian (represented by j and h) instead of using the relative radius and angle degree to simplify understanding. In the literature, a method for drawing radar diagrams online with the Y-index is also lacking. This study was conducted to enhance the Y-index with an additional relative radius denoted by k and the angle degree represented by h* (named Yk-index), include easy-to-use features (e.g., copying and pasting) for the delivery of the online Radar-Yk, and identify which one of AIC/R contributed the most to a scientific journal. Methods: From the Web of Science (WoS) database, we downloaded 9498 abstracts of articles published in the journal of Medicine (Baltimore) in 2020 and 2021. Three visual representations were used, including a Sankey diagram, a choropleth map, and a radar diagram, to identify the characteristics of contributions by AIC/R to Medicine (Baltimore) using the Yk-index (j, k, h*). A demonstration of Rada-Yk with easy-to-use features was given using the copy-and-paste technique. Results: We found that Qiu Chen (China), Sichuan University (China), China, and South Korea (based on regions, e.g., provinces/metropolitan areas in China) were the most productive AIC/R, with their Yk equal to 27,715, 12415.1, and 2045, respectively; a total of 85.6% of the published articles in Medicine (Baltimore) came from the 3 countries (China, South Korea, and Japan); and this method of drawing the Radar-Yk online was provided and successfully demonstrated. Conclusion: A breakthrough was achieved by developing the online Radar-Yk to show the most contributions to Medicine (Baltimore). Visualization of Radar-Yk could be replicated for future academic research and applications on other topics in future bibliographical studies.

“…Largest number of corresponding-author (RP) and first-author (FP) publications in the ophthalmology category was published by just four of the top 23 highly cited authors (17% of the 23 authors). Compared to the categories of anesthesiology (50%) and emergency medicine (62%) [36] , the proportion of authors with similar FP and RP was lower. The top 52 authors all had RPs greater than FP.…”

“…Documents with a TC 2020 ≥100 were selected as HCAs in this study. The SCI-EXPANDED document material was reviewed, imported into Microsoft Excel 365, and supplementary coding was performed manually for all the analyses [36][37] . The productivity of nations and institutes in terms of publications was assessed using six publication metrics [34,38] : TP: total number of publications, IP: number of singleinstitution publications (IP I ) or single-country authored publications (IP C ), CP: number of inter-institutionally collaborative publications (CP I ) or internationally collaborative publications (CP C ), FP: number of first-author publications, RP: number of corresponding-author publications, SP: number of single-author publications.…”

“…The performance of the authors in terms of publications was assessed using the Y-index. A formula for the Y-index is as [33,36] Y-index (j, h), where j is a constant linked to publishing potential and represents the sum of corresponding-author publications (RP) and first-author publications (FP), and h is a constant related to publication characteristics and represents the polar angle around the ratio of RP to FP. The higher the j value, the greater the corresponding author and first author contribute to the papers.…”

AIM: To determine and evaluate the features of highly cited articles (HCAs) in the ophthalmology category in the Science Citation Index Expanded (SCI-EXPANDED) from 1991 to 2020. METHODS: The Web of Science Core Collection documents with at least 100 citations from their publication year until December 31, 2020, were evaluated as highly cited. The examined features were the distribution of yearly output and its average number of per publication, HCAs, authors, institutions, journals, and nations. The publication performance of nations and organizations was assessed using six publication indicators. The Y-index was employed to compare the research outputs of various authors. RESULTS: Publications that had cited the most references were highly published in high-impact factor journals. The United States of America came out on top across all six publication indicators, and it was home to eight of the top 10 most productive institutions. The articles written by Breivik et al (2006) and Farrar et al (2001) were highly cited and had a significant impact in 2020. The authors had a higher number of highly cited articles published as corresponding authors than as first authors. CONCLUSION: The findings of the present study highlight the current scope of global research in ophthalmology. The findings can help policy-makers and advisory groups of research centers to develop future policies. In addition, the findings can guide researchers in this field.

Background The widespread use of mobile technologies in health care (mobile health; mHealth) has facilitated disease management, especially for chronic illnesses such as diabetes. mHealth for diabetes is an attractive alternative to reduce costs and overcome geographical and temporal barriers to improve patients’ conditions. Objective This study aims to reveal the dynamics of scientific publications on mHealth for diabetes to gain insights into who are the most prominent authors, countries, institutions, and journals and what are the most cited documents and current hot spots. Methods A scientometric analysis based on a competitive technology intelligence methodology was conducted. An innovative 8-step methodology supported by experts was executed considering scientific documents published between 1998 and 2021 in the Science Citation Index Expanded database. Publication language, publication output characteristics, journals, countries and institutions, authors, and most cited and most impactful articles were identified. Results The insights obtained show that a total of 1574 scientific articles were published by 7922 authors from 90 countries, with an average of 15 (SD 38) citations and 6.5 (SD 4.4) authors per article. These documents were published in 491 journals and 92 Web of Science categories. The most productive country was the United States, followed by the United Kingdom, China, Australia, and South Korea, and the top 3 most productive institutions came from the United States, whereas the top 3 most cited articles were published in 2016, 2009, and 2017 and the top 3 most impactful articles were published in 2016 and 2017. Conclusions This approach provides a comprehensive knowledge panorama of research productivity in mHealth for diabetes, identifying new insights and opportunities for research and development and innovation, including collaboration with other entities, new areas of specialization, and human resource development. The findings obtained are useful for decision-making in policy planning, resource allocation, and identification of research opportunities, benefiting researchers, health professionals, and decision makers in their efforts to make significant contributions to the advancement of diabetes science.
