ALTMETRIC ANALYSIS OF THE MOST-CITED 100 ARTICLES ON THE RETINA PUBLISHED BETWEEN 2010 AND 2020

A comparison of the top 500 papers in Clinical Nutrition ranked by citation and Altmetric Attention Scores

BACKGROUND AND AIMS

Citation scores (CS) have been traditionally used to measure the impact of scientific publications. Sourced from the Internet, Altmetric Attention Scores (AAS) are complementary metrics that assess how often publications are discussed and used globally. We compared by rank the top 500 papers by CS and AAS published in Clinical Nutrition with corresponding AAS and CS.

METHODS

A search for all publications in Clinical Nutrition was performed on Dimensions (https://app.dimensions.ai/discover/publication) on 3rd April 2024. Outputs were ranked according to CS and then by AAS with the top 500 in each category selected. Scores, year and type of publication were recorded. Correlation was expressed as the Spearman's rank coefficient (ϱ).

RESULTS

We identified 18,790 outputs. Within the top 500 publications ranked by CS, there was a significant weak positive correlation (ϱ = 0.235, P < 0.0001) between CS [median (IQR) 149 (116-223)] and AAS [7 (3-22)]. Ranked by AAS, there was a non-significant very weak positive correlation (ϱ = 0.072, P = 0.106) between AAS [55.5 (36-115)] and CS [42 (16.5-94.5)]. Trends remained similar when grouped by publication type. Guidelines, ranked by CS, had the highest CS and ranked by AAS, the highest CS and AAS. Publications per year, by year, ranked by CS, had a negatively skewed distribution peaking in 2012 and declined thereafter, but when ranked by AAS, had a moderately positive linear trend from 2001 to 2024 (ϱ = 0.513, P < 0.0001).

CONCLUSION

Correlation between CS and AAS was weak. Guidelines had the highest CS and AAS. CS are iterative taking years to mature while AAS are immediate.

Drug-eluting stents for coronary artery disease in the perspective of bibliometric analysis

Drug-eluting stents (DES) play a crucial role in treating coronary artery disease (CAD) by preventing restenosis. These stents are coated with drug carriers that release antiproliferative drugs within the vessel. Over the past two decades, DES have been employed in clinical practice using various materials, polymers, and drug types. Despite optimizations in their design and materials to enhance biocompatibility and antithrombotic properties, evaluating their long-term efficacy and safety necessitates improved clinical follow-up and monitoring. To delineate future research directions, this study employs a bibliometric analysis approach. We comprehensively surveyed two decades' worth of literature on DES for CAD using the Web of Science Core Collection (WOSCC). Out of 5,778 articles, we meticulously screened them based on predefined inclusion and exclusion criteria. Subsequently, we conducted an in-depth analysis encompassing annual publication trends, authorship affiliations, journal affiliations, keywords, and more. Employing tools such as Excel 2021, CiteSpace 6.2R3, VOSviewer 1.6.19, and Pajek 5.17, we harnessed bibliometric methods to derive insights from this corpus. Analysis of annual publication data indicates a recent stabilisation or even a downward trend in research output in this area. The United States emerged as the leading contributor, with Columbia University and CRF at the forefront in both publication output and citation impact. The most cited document pertained to standardized definitions for clinical endpoints in coronary stent trials. Our author analysis identifies Patrick W. Serruys as the most prolific contributor, underscoring a dynamic exchange of knowledge within the field.Moreover, the dual chart overlay illustrates a close interrelation between journals in the "Medicine," "Medical," and "Clinical" domains and those in "Health," "Nursing," and "Medicine." Frequently recurring keywords in this research landscape include DES coronary artery disease, percutaneous coronary intervention, implantation, and restenosis. This study presents a comprehensive panorama encompassing countries, research institutions, journals, keyword distributions, and contributions within the realm of DES therapy for CAD. By highlighting keywords exhibiting recent surges in frequency, we elucidate current research hotspots and frontiers, thereby furnishing novel insights to guide future researchers in this evolving field.

Modern Impact of Surgery Journals: Associations Between Impact Factor, H5-Index, and Altmetric Score

INTRODUCTION

While impact factor (IF) remains the "gold standard" metric for journal quality, newer metrics are gaining popularity. These include the H5-index and journal Altmetric Attention Score (AAS). We explored the relationship between the IF, H5-index, and AAS for core general surgery (GS) and subspecialty journals.

METHODS

For all GS and subspecialty journals with a Clarivate IF, H5-index (January 1, 2017, to December 31, 2021) and journal AAS were obtained. Journal Twitter presence and activity was sourced from Twitter and the Twitter application programming interface. Spearman's correlations were assessed for numeric variables.

RESULTS

A total of 105 journals were included, around half (49/105; 46.7%) of which were core GS journals. Median IF was 2.48 and median H5-index 19. Journal IF demonstrated a strong correlation with H5-index overall (r = 0.81), though this ranged from r = 0.95 (P < 0.01) for vascular surgery to r = 0.77 (P < 0.01) for plastic surgery journals. AAS was moderately correlated with the IF and H5-index (r = 0.59 and 0.62, respectively; both P < 0.01). R² values ranging indicated that 66% of the variation in the H5-index and 35% of the variation in AAS was explained by the IF. Just over half the journals had a Twitter account (54/105; 51.4%). Journals with a Twitter account also had a significantly higher IF, H5-index, and AAS than those without a Twitter account (all P < 0.01). AAS was moderately correlated with Twitter activity (r = 0.59) and Twitter followers (r = 0.69).

CONCLUSIONS

Across GS and subspecialty journals, journal IF correlates strongly with the H5-index and moderately with AAS. However, only 35% of variation in AAS and 66% of variation in the H5-index is explained by the IF, indicating that these metrics measure unique aspects of journal quality. The future growth of surgical journals should be geared towards improving across multiple metrics, including both the conventional and the contemporary, while leveraging social media to improve readership and eventual academic impact.

Top 50 most-cited articles on SMILE surgery between 2010 and 2022: a correlation comparison between conventional bibliometrics and current altmetrics of research impact

PURPOSE

To conduct a bibliometric and altmetric analysis of the top 50 most-cited articles on small incision lenticule extraction (SMILE) surgery and assess its correlations with other metrics.

METHODS

The terms "small incision lenticule extraction" or "SMILE" were searched in the title, abstract, and keywords using Web of Science database. The retrieved articles (n = 927, between 2010 and 2022) were analyzed in-depth using altmetric attention scores (AAS), and traditional metrics (citation numbers of articles, impact factor of journals, and other citation-based metrics). A correlation statistics was performed with metrics. The articles' focus was examined quantitatively and the most prolific parameters were identified. Authorship network and country statistics also was examined.

RESULTS

Citation numbers were between 491 and 45. AASs were between 26 and 0. The altmetric score correlated moderately with citation number (r = 0.44, P = 0.001) and annual mean citations (r = 0.49, P < 0.001), but correlated weakly with impact factor (r = 0.28, P = 0.045), and immediacy index (r = 0.32, P = 0.022). The most articles published from China and the most articles were published in 2014. Modern SMILE surgery was mostly compared to the older LASIK procedure. The highest authorship number of links belonged to Zhou XT.

CONCLUSION

The first bibliometric and altmetric analysis of SMILE research provides novel directions for future work by showing the current research trends, prolific parameters, and zones with potential for the public's attention, providing useful information about the dissemination of scientific knowledge on SMILE in social media and to the general public.

Altmetric and Bibliographic Analysis of the Most Popular Articles on Vitreoretinal Surgery Between 2010 and 2020

Purpose Altmetrics is a web-based metrics method that measures the online dissemination of an article and the interactions it receives. We aimed to perform a bibliometric and altmetrics analysis of the 100 most cited articles (T100) on vitreoretinal surgery (VRS) published between 2010 and 2020. Methods A detailed search including terms regarding VRS in the Web of Science database was conducted. Articles were examined for bibliometric data and altmetrics. Results T100 articles had citation numbers ranging from 55 to 368 and altmetrics score (AS) values ranging from 0 to 125, and there was no statistically significant correlation between them. AS was weakly correlated with publication year. A statistically weak negative correlation was also found between AS and percent of citable open access, number of years since publication (NYsP), and average citations per year (ACpY). Conclusion AS values of articles on VRS were found to be low. Apparently, this was because the issue was of a highly specific and technical nature. However, the existence of articles with a zero AS value despite high citation numbers suggests that journals and authors do not yet attach enough importance to altmetrics. Altmetric analysis is not a reliable indicator for evaluating the scientific value of an article, and it cannot be a substitute for traditional metrics but it can provide perspective on the social impact of articles.

Sparking attention on African swine fever research on social media platform: An altmetric evaluation of top 100 highly cited articles

African swine fever (ASF) is one of the highly contagious diseases of pigs that affect both domestic and wild pigs. The primary purpose of this research was to evaluate the online social attention on the ASF research to inform the research scientists and key stakeholders in the field by reporting the concise information of the most influential articles, social engagement, and impacts of the research. This study employed the altmetrics tool to evaluate the research papers. Bibliographic data of 100 articles were collected from Scopus; altmetric data was collected from the Altmetric.com database and analyzed using SPSS and Tableau. The articles were mainly mentioned on Twitter, followed by News Outlets and significant readers on Mendeley. Pearson correlation coefficients revealed a weak and insignificant correlation between Scopus Citation and Altmetric Attention Score (AAS). Mendeley Readership and Scopus Citation were moderately correlated. However, there was a significant positive correlation between the AAS and Mendeley readership. Using altmetric tools, the paper is the first research to shed light on the characteristics of ASF on social media.

Top 50 Most-Cited Publications on Blepharoplasty Surgery Between 2015 and 2022: From a Current Altmetric Perspective of Research Impact

Background Blepharoplasty is one of the most-performed esthetic operations, and social media platforms have become an influential tool for distributing scientific information. Because the internet has gained popularity among medical experts and surgeons to connect with the public, we aimed to evaluate the altmetric–bibliometric analysis of the top 50 most-cited articles on blepharoplasty surgery between 2015 and 2022 and assess correlations with various metrics.

Methods “Blepharoplasty” was searched using the WoS database, and the altmetric score was obtained. Co-authors, keywords, country of authors, and cited journal network map analysis were created using VOSviewer for the 485 publications retrieved. The articles' focus was examined quantitatively and the most prolific parameters were identified.

Results The most research was performed by the USA, the most productive institution was the “University of California System,” and the most prolific author was “Wonn CH.” The number of citations ranged from 37 to 9, and altmetric attention scores ranged from 54 to 0. The most articles and citations peaked in 2021. Altmetric and Twitter scores were moderately correlated with journal metrics but there were no correlations with citation counts.

Conclusion The first comprehensive altmetric analysis on blepharoplasty surgery offers new guidelines for upcoming articles by demonstrating the recent investigation trends, prolific parameters, and zones with potential for the public's attention and education, providing valuable data regarding the distribution of scientific knowledge in social media platforms and to the general public. A social network may be used to increase the visibility of scientific articles apart from creating brands and markets.

An Analysis of the 50 Most-Cited "Uveitis" Articles Published Between 2010-2020 From a Bibliographic and Altmetric Perspective

Purpose We aimed to evaluate the 50 most-cited articles on uveitis according to their Altmetric Attention Score (AAS) and additional metrics. Methods The Web of Science (WoS) core collection database was used in this study. The article and journal metrics and characteristics were examined. In addition, the effect of article and journal metrics on the AAS was examined with multivariate adaptive regression splines (MARS). Results The number of citations of the evaluated articles ranged from 670 to 90, and AASs ranged from 633 to 0. According to the MARS model, the importance scores of the predictors were as follows: article influence score (100%), immediacy index (77.74%), number of years since publication (57.79%), times cited in WoS (32.69%). We found that the trend of articles on uveitis was related to the "treatment category", namely, adalimumab. Second, the popular topic was uveitis caused by viruses. Conclusions We found that citation-based metrics and year of publication contributed to AAS. AAS appears to be inadequate in assessing the quality of articles. However, due to the electronic transformation of the publishing industry, it seems inevitable that altmetrics will become an additional supportive metric.

Correlation Between Altmetric Attention Scores and Citations for Articles Published in High-Impact Factor Ophthalmology Journals From 2018 to 2019

Importance

The Altmetric attention score (AAS) provides new information to gauge the impact of a research article not found through typical metrics, such as impact factor or citation counts.

Objective

To explore the association between AAS and common impact markers among high-impact ophthalmology journals from 2018 to 2019.

Design, Setting, and Participants

All articles published in the American Journal of Ophthalmology (AJO), JAMA Ophthalmology (JAMAO), and Ophthalmology (OPH) from January 1, 2018, to December 31, 2019, were collected for this cross-sectional study. Excluded articles were those missing Altmetric data at the time of data collection. The AAS and associated social media impact for each article were collected with the AAS calculator bookmarklet. Spearman rank correlation analyses and analysis of variance tests were conducted to assess differences in various metrics between AJO, JAMAO, and OPH. The study included articles published of all document types (article, conference paper, editorial, erratum, letter, note, retracted, review, and short survey) and access status (open access and not open access).

Main Outcomes and Measures

The correlation between citation counts and Altmetric variables including AAS.

Results

A total of 2467 articles were published in the study period. There were 351 articles excluded owing to missing Altmetric data. Of the 2116 articles included in the analysis, 1039 (49.1%) were published in 2018, and 1077 (50.9%) were published in 2019; the mean number of citations was 8.8 (95% CI, 7.9-9.6) for AJO, 6.2 (95% CI, 5.3-7.1) for JAMAO, and 15.1 (95% CI, 13.3-17.0) for OPH. The mean AAS was 4.5 (95% CI, 3.3-5.6) for AJO (723 publications), 27.4 (95% CI, 22.1-32.8) for JAMAO (758 publications), and 15.1 (95% CI, 10.9-19.3) for OPH (635 publications). Citation rate was moderately correlated with AAS across the 3 journals (AJO, ρ = 0.39; P < .001; JAMAO, ρ = 0.41; P < .001; OPH, ρ = 0.40; P < .001), as well as minimally or moderately correlated with engagement or mention by Facebook posts (AJO, ρ = 0.38; P < .001; JAMAO, ρ = 0.24; P < .001; OPH, ρ = 0.20; P < .001), news outlet reporting (AJO, ρ = 0.12; P < .001; JAMAO, ρ = 0.38; P < .001; OPH, ρ = 0.19; P < .001), and Twitter posts (AJO, ρ = 0.40; P < .001; JAMAO, ρ = 0.38; P < .001; OPH, ρ = 0.42; P < .001).

Conclusions and Relevance

Results of this cross-sectional study suggest that citation rate has a moderate positive correlation with online and social media sharing of research in ophthalmology literature. Peer-reviewed journals may increase their reach and impact by sharing their literature through social media and online platforms.
