Abstract: PRINCIPLES: Citation metrics are commonly used as a proxy for
scientific merit and relevance. Papers published in English, however, may exhibit
a higher citation frequency than research articles published in other languages,
though this issue has not yet been investigated from a Swiss perspective
where English is not the native language.
METHODS: To assess the impact of publication language on citation frequency
we focused on oral surgery papers indexed in PubMed MEDLINE that were
published by Swiss Dental Schools between 2002 and 2007. Citation frequency
of research papers was extracted from the Institute for Scientific Information
(ISI) and Google Scholar database. An univariate and multivariate logistic
regression model was used to assess the impact of publication language
(English versus German/French) on citation frequency, adjusted for journal
impact factor, number of authors and research topic.
RESULTS: Papers published in English showed a 6 (ISI database) and 7 (Google
Scholar) times higher odds for being cited than research articles published in
German or French.
CONCLUSIONS: Our results suggest that publication language substantially
influences the citation frequency of a research paper. Researchers should
publish their work in English to render them accessible to the international
