To identify the worldwide bibliometric characteristics of research on SARS-CoV-2 infection and cerebrovascular disease.
A retrospective, descriptive, and bibliometric study was performed. We analyzed 1834 publications about COVID-19 and cerebrovascular disease from the Scopus database considering the time since the beginning of the pandemic between 2019 and 2020. Bibliometric indicators were evaluated such as number of citations, citations per publication by authors, countries, journals, and collaborations at national, international, institutional, and impact levels according to Cite Score Quartile and h-index metrics. All analysis was performed using SciVal software.
The highest percentage of articles corresponded to universities in the United States, including Harvard and New York with 59 and 20 publications, respectively, and the University of Toronto in Canada with 22 publications. In relation to citation indicators, journals such as Stroke and Journal Stroke and Cerebrovascular diseases obtained 1971 and 561 citations, respectively. Regarding collaboration indicators, the national collaboration index was 39.4% and the institutional collaboration index was 31.1%. Finally, neurology, cardiovascular medicine, and cardiology and surgery were the subject areas with the highest research results, with 424, 217, and 128 studies, respectively.
It was observed that the United States was the country with the highest scientific production on COVID-19 and cerebrovascular disease in the year 2020 in the different health areas; however, more research is still needed worldwide for a better analysis of the bibliometric indicators on the subject.
确定全球范围内关于 SARS-CoV-2 感染与脑血管疾病研究的文献计量学特征。
本回顾性、描述性和文献计量学研究对 2019 年至 2020 年大流行期间从 Scopus 数据库中分析了 1834 篇关于 COVID-19 和脑血管疾病的出版物。评估了文献计量学指标，如引用次数、作者发表的论文引用次数、国家、期刊以及国家、国际、机构和影响力层面的合作情况，根据 Cite Score 四分位和 h-index 指标进行评估。所有分析均使用 SciVal 软件进行。
发表论文最多的是美国的大学，包括哈佛大学（59 篇）和纽约大学（20 篇），以及加拿大的多伦多大学（22 篇）。在引文指标方面，Stroke 和 Journal Stroke and Cerebrovascular diseases 这两个期刊分别获得了 1971 次和 561 次引用。在合作指标方面，国家合作指数为 39.4%，机构合作指数为 31.1%。最后，神经科、心血管医学和心脏病学与外科学是研究成果最高的三个领域，分别有 424、217 和 128 项研究。
2020 年，美国在不同卫生领域的 COVID-19 和脑血管疾病的科学研究产出最高，但全球仍需要更多的研究来更好地分析该主题的文献计量学指标。
