ABSTRACT:       AIM: To analyze papers published in the World Journal of 
Gastroenterology (WJG) from 2006 to 2007. We investigated the highly 
cited papers for geographic distribution of the cited authors, as well as 
the distribution of the citing journals and year of citation. 

METHODS: Papers published in WJG from 2006 to 2007 and their citations 
were retrieved from the Science Citation Index Expanded (SCIE). The 
papers and their citations were analyzed according to bibliometric 
methods, including the number of citations for a given paper, the 
distribution of the highly cited papers, the geographic distribution of 
the cited authors, and the years of citation. 

RESULTS: Two thousand five hundred and six papers published in WJG from 
2006 to 2007 were collected through SCIE, and 2335 of these were 
categorized as articles, reviews or proceedings. In 2006 and 2007, the 
average citation rate was 85.08% and 70.48%, respectively, and the 
average number of citations per paper was 4.33 and 2.51. Among the 2506 
papers, 1963 were cited 8788 times by other articles. The mean number of 
citations per paper was 3.51. The papers with over three citations 
accounted for 54.72% of all those that were cited, and the total number 
of citations accounted for 85.38% of the total of 8788 citations. 
Thirteen papers were cited over 30 times and the highest number of 
citations for any one paper was 98. The cited authors came from 70 
different countries or regions, with China, Japan and the United States 
being the most frequent. The highest average citation rate and number of 
citations per paper were for authors from Canada (96.30%, 6.89), Hungary 
(92.31%, 5.62), Australia (88.46%, 5.46), Germany (87.04%, 5.33), and 
Spain (87.50%, 5.11). The impact factor was 2.081 and the self-citation 
rate was 9.41% in 2008. The papers published in WJG in 2006-2007 were 
cited by 1597 journals. 

CONCLUSION: The papers in WJG have a high number of citations, and have 
been cited in numerous journals by authors from various countries. The 
results imply that WJG has an influential academic profile in 
gastroenterology around the world. (C) 2009 The WIG Press and Baishideng.
