Objective To compare articles published in global primary journals titled “evidence-based” via bibliometric analysis in order to provide suggestion for evidence-based research and development of related journals.
Methods We searched electronic databases to retrieve global primary journals titled “evidence-based”, and collected their impact factors, article click, download and citation frequency through the journal’s website and related citation databases.
Results Three English and 4 Chinese primary journals titled “evidence-based” met the inclusion criteria. (1) Citation frequency: Evidence-Based Complementary amp; Alternative Medicine and Worldviews on Evidence-Based Nursing were indexed by SCI with impact factor over 1 (5th and 13th in relevant subject category), and their immediacy index was about 7 times as much as that of Chinese journals (0.2 vs 0.03). Chinese Journal of Evidence-Based Pediatrics (CJEBP) had the highest impact factor among 4 Chinese journals (0.946, 23rd in the relevant subject category), while Chinese Journal of Evidence-Based Medicine had the highest immediacy index with 0.07; (2) Download frequency: Journal of Evidencebased Medicine (JEBM) had the highest download frequency per article in database (72 vs 23), but the website download frequencies per article of CJEBM and CJEBP were about 5 to 6 times as much as that of database; (3) Number of articles published: Two English journals published the fewest articles but with the highest impact factors. Chinese Journal of Evidence-Based Medicine had the 2nd highest impact factor although published the most articles, as well as the highest download frequency and immediacy index among the 4 Chinese journals. It suggested that there was no direct relationship between the number of the published articles and the impact factor of a journal.
Conclusion The impact of English journals is better than that of Chinese journals. CJEBM and CJEBP are the top 2 ones among the Chinese journals with open access websites. The selection of articles should be driven by readers’ demand, and the impact of journals could be improved by online publication with open access.
