Résumé
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.

BACKGROUND
BACKGROUND
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.
METHODS
METHODS
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.
RESULTS
RESULTS
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.
CONCLUSIONS
CONCLUSIONS
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.
