  • Title: Brazilian medical publications: citation patterns for Brazilian-edited and non-Brazilian literature.
    Author: Cunha-Melo JR, Santos GC, Andrade MV.
    Journal: Braz J Med Biol Res; 2006 Aug; 39(8):997-1002. PubMed ID: 16906273.
    Abstract:
    Today, the quality of a scientific article depends on the periodical in which it is published and on the number of times the article is cited in the literature. In Brazil, the criteria for the evaluation of this scientific production are improving. However, there is still some resistance, with authors arguing that Brazilian publications must be preferentially addressed to the national readers and, therefore, they should ideally be written in Portuguese. In order to determine the kind of scientific journals cited in the reference lists of articles published in medical periodicals edited in Brazil, in the present study we determine the rate of Portuguese/English citations. Three issues of 43 periodicals (19 indexed in SciELO, 10 in PubMed, 10 in LILACS, and 4 in the ISI-Thompson base) of different medical specialties were analyzed, and the number of both Portuguese and English citations in the reference list of each article was recorded. The results showed that in Brazilian-edited journals the mean number of citations/article was 20.9 +/- 6.9 and the percentage of citations of international non-Brazilian periodicals was 86.0 +/- 11.2%. Of the latter, 94.4 +/- 7.0 are indexed by ISI-Thompson. Therefore, we conclude that Brazilian medical scientists cite the international non-Brazilian periodicals more than the national journals, and most of the cited papers are indexed by ISI-Thompson.
