Purpose: To determine the association between language and number of citations of ophthalmology articles published in Brazilian journals. Methods: This study was a systematic review. Original articles were identified by review of documents published at the two Brazilian ophthalmology journals indexed at Science Citation Index Expanded -SCIE ["Arquivos Brasileiros de Oftalmologia (ABO)" and "Revista Brasileira de Oftalmologia (RBO)"]. All document types ("articles" and "reviews") listed at SCIE in English (English Group) or in Portuguese (Portuguese Group) from January 1, 2008 to December 31, 2009 were included, except: "editorial materials"; "corrections"; "letters"; and "biographical items". The primary outcome was the number of citations through the end of second year after publication date. Subgroup analysis included likelihood of citation (cited at least once versus no citation), journal, and year of publication.
Conclusion:The number of citations of articles published in Portuguese at Brazi lian ophthalmology journals is lower than the published in English. The results of this study suggest that the editorial boards should strongly encourage the authors to adopt English as the main language in their future articles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
