Social attention and scientific articles on stroke: Altmetric analysis of top-50 articles
Introduction
The number of times that published articles are cited is generally used to measure the impact of a journal and to evaluate the competence of authors. A citation is a reference to a published or unpublished source, and is based on the bibliometrics that explored these associations. This analysis is used to rank articles, with the citation rank used to identify published output that has had the greatest intellectual impact. Many medical specialists use bibliometric analysis to identify the most significant papers in their field, such as general surgery [1], emergency surgery [2], and neurology [3]. However, citations take a long time to accumulate, and the total number of citations may be affected by the time that has elapsed since publication.
A new Web-based metric (Altmetrics) has led to fast and dynamic analyses of the influence on social media platforms such as Facebook and Twitter. Social media is well known to influence politics and the economy, and has also received considerable attention from different perspectives in various medical fields. The aim of this study was to determine which recent papers in the field of stroke have received the highest Altmetric Attention Scores (AASs).

Results
Altmetric Explorer identified 43,410 articles as being referred to online. The AAS, journal name, IF ranking, publication year, numbers of citations, and numbers of annual citations of the top-50 articles are summarized in Table 1. Because Altmetrics started collecting data only during the second half of 2011, none of the articles before 2010 were listed. The number of papers on this list peaked in 2016 (Supplementary Fig. I). Sixteen articles originated from the Stroke journal, accounting for
Discussion
To the authorsā knowledge, this is the first study to evaluate the online attention received by articles published in the stroke field. The journals that published articles receiving the most attraction on social media were Stroke (nāÆ=āÆ16) and the New England Journal of Medicine (nāÆ=āÆ8). Twenty-one articles were on the subtypes of IS. Regarding contents, treatment and management and risk factors for stroke received the most attention. It is noteworthy that about half of the top-10 ranked

How do scientific papers from different journal tiers gain attention on social media?
2023, Information Processing and ManagementCitation Excerpt :Burst, defined as āshort periods of intensive activity followed by long periods of inactivityā (BarabĆ”si, 2005), is a common phenomenon in many complex systems in human activities. The bursty nature of human behavior has been widely observed and studied in various domains, such as stocking trade (Zhu & Shasha 2003), electronic communication (Karsai et al., 2012), biological neural network (Kim et al., 2019), as well as the propagation of information on social media (Notarmuzi et al., 2022). The bursty activity of information propagation on social media is defined as a sequence of collective behavior propagation such as tweeting and retweeting (Zhan et al., 2020).

2021, Arthroscopy - Journal of Arthroscopic and Related SurgeryCitation Excerpt :The push to generate social media traffic by the same researchers that ultimately cite these publications may contribute to a cyclical and artificial inflation of the AAS. In contrast, several studies have found AAS and traditional biometrics to be only weakly associated.28,39-43 Most notably, Barakat et al.28 found that the AASs of articles in NEJM, Lancet, and JAMA were poorly correlated with citation rate 3 years after initial publication.
