Abstract

Background: In May 2006, a search was conducted of the 20 highest cited articles related to Evidence Based Medicine (EBM) through MEDLINE Publication Types. The New England Journal of Medicine's (N Engl J Med's) and Lancet's articles were cited for the most part in the top cited twenty articles. Therefore, an investigation with the highest Impact Factors of the top three cited journals was carried out. Moreover, MEDLINE's Publication Type data was added.Purpose: This article explains that the cluster of highest cited articles was related to EBM. Bibliometric analysis of the N Engl J ed, JAMA and Lancet was used, which had more than 3800 articles or reviews from 2002 to 2004 in the “Web of Science”.Method: The category “MEDICINE, GENERAL & INTERNAL ”of“ Journal Citation Reports” was searched with the highest Impact Factor of the three journals' articles cited the most times by using the Web of Science's General Search. Further to that, the MEDLINE's Publication Type was searched to find a relation to EBM articles, Reviews, or other Publication Types, for example, a Comparative Study, and so on.Results:1: The articles of N Engl J Med were quoted 1.5 times for the three journals over three years. EBM related articles were cited from 2.3 to 3.0 times. Review articles, however, were cited 0.95 times.2: The articles of JAMA were quoted 0.9 times for the three journals during three years. EBM related articles were cited from 1.7 to 1.4 times. Practice Guideline articles were cited 9.3 times.3: The articles of Lancet were quoted 0.7 times for the three journals over three years. EBM related articles were cited from 1.2 to 1.6 times.Conclusion: It was proven that EBM relation Publication Type articles were quoted more often than in any other article.
