Stroke is a leading cause of mortality and disability worldwide. Research activity in Latin American countries might be the key to solving, or at least improving, the understanding of stroke-related issues in the region. Our aim was to describe and analyze the research output on stroke in Latin America.
We performed a bibliometric analysis of studies on stroke in Latin America reported from 2003 to 2017 in Scopus-indexed journals. We extracted the annual research, countries, journals, authors, institutions, citation frequency, and journal metrics. The data were quantitatively analyzed. Publication activity was adjusted to the countries by population size. Also, the results from an author and country co-occurrence analysis are presented as network visualization maps using VOSviewer.
A total of 2298 Latin American stroke-related reports were identified, most were original research reports (72%). The number of reported studies had increased from 2003 to 2017 (P < 0.001). Brazil was the country with the greatest production with 1273 reports (55.4%), followed by Argentina and Mexico. No association was found between stroke prevalence and mortality and the scientific production of the country. Six universities and three hospitals were the most prolific institutions. A collaborative relationship was found between the United States and Brazil, Argentina, and Mexico. The intraregional collaboration of research on stroke was low among Latin American countries.
Despite the continuous increase in research output from Latin American countries, more effort is needed to strengthen the research capacity by developing networks and collaborative research projects, ideally among the Latin American countries themselves.
中风是全球范围内导致死亡和残疾的主要原因。拉丁美洲国家的研究活动可能是解决（或至少改善）该地区与中风相关问题的关键。我们的目的是描述和分析拉丁美洲中风研究的产出。
我们对 2003 年至 2017 年在 Scopus 索引期刊上报告的拉丁美洲中风研究进行了文献计量学分析。我们提取了年度研究、国家、期刊、作者、机构、引用频率和期刊指标。对数据进行了定量分析。根据人口规模调整了各国的研究活动。此外，还使用 Vosviewer 以网络可视化地图的形式展示了作者和国家共现分析的结果。
共确定了 2298 篇与拉丁美洲中风相关的报告，其中大部分为原始研究报告（72%）。报告的研究数量从 2003 年到 2017 年有所增加（P<0.001）。巴西是产量最大的国家，有 1273 篇报告（55.4%），其次是阿根廷和墨西哥。中风患病率和死亡率与国家的科学产量之间没有关联。六所大学和三家医院是最多产的机构。发现美国与巴西、阿根廷和墨西哥之间存在合作关系。拉丁美洲国家之间的中风研究区域内合作程度较低。
尽管拉丁美洲国家的研究产出持续增加，但仍需加强研究能力，通过发展网络和合作研究项目来加强研究能力，理想情况下是在拉丁美洲国家之间进行。
