Do Brazilian medical journals reference Brazilian articles? A cross-sectional study.

Background: The quantity and quality of Brazilian scientific output increases decade by decade. However, there is a tendency to undervalue Brazilian journals, illustrated by the low number of citations compared with texts in international journals, with the tacit justification that foreign articles are of superior quality. Objectives: To investigate the differences in numbers of citations of Brazilian and international periodicals in three Brazilian journals from 2016 to 2020. Methods: All articles published in the Journal of the Brazilian College of Surgeons, in the Jornal Vascular Brasileiro, and in Acta Cirúrgica Brasileira from 2016 to 2020 were analyzed. The references of these studies were analyzed, summing the total number of citations and classifying them as published in Brazilian or foreign journals. Results: A total of 902 articles were analyzed, totaling 23,394 references, with a mean of 25.81 ± 8.59 references per article. Of these, 2,680 (11.45%) were Brazilian, equating to a mean of 2.95 ± 3.79 Brazilian references per article. Conclusions: It is necessary to improve appreciation of Brazilian periodicals, especially among Brazilian researchers and institutions responsible for science funding.
