title: [Impact of the inclusion of articles written in English in multilingual Spanish biomedical journals].
abstract: OBJECTIVE
  To analyze the impact of articles published in English compared to those published in Spanish in multilingual Spanish biomedical journals.
  
  
  METHODS
  We analyzed the language of publication, the number of original articles, the nationality of the authors, the citations received, the citing article and the nationality of the citing authors among the articles published from 2008-2012 in 5 multilingual Spanish biomedical journals.
  
  
  RESULTS
  The study included 4,296 documents, 85 of which were published in English (2%). The percentage of original articles and of non-Spanish authorship was significantly higher among these latter articles and they also achieved more citations and more citing articles per article published.
  
  
  CONCLUSIONS
  The proportion of articles published in English by multilingual Spanish biomedical journals is low and they are more often originals signed exclusively by foreign authors and receive more citations than those published in Spanish, which are also more frequently made by foreign authors.
