An analysis of randomized control trials articles published from 2004-2009 in Chinese Journal of Hepatobiliary Surgery

Objective To study the academic level of randomized control trials(RCTs)published from 2004 to 2009 in Chinese Journal of Hepatobiliary Surgery.Methods Published work about RCTs in 72 issues of Chinese Journal of Hepatobiliary Surgery was searched by finding relevant articles published during 2004-2009.Correlated indexes including literature received time, literature publishing time, the total number of citations, number of citations in Chinese, number of citations in English, research funding situations, the number of authors, article affiliations in all RCTs, together with single(or multiple)center study situation, positive conclusions, the starting time, the end time,and number of patients recruited in clinical RCTs were extracted for aggregate analysis.Results During the past six years, a total of 135 articles of RCT were published in Chinese Journal of Hepatobiliary Surgery, accounting for 8.7% in all clinical studies.The average number of RCTs in each issue was 1.88.The average time for publishing time delay was 450 days.The total number of citations in RCTs was 1252 and the average number of RCTs for citations was 9.3.53 RCT studies were financed, accounting for 39% of the total number of research papers.Beijing Friendship Hospital attached to the Capital University of Medical Sciences had published 8 papers of RCT and it is the institution of publishing the largest number of such papers in the journal.The number of multi-center study for RCTs was one and all RCT studies had significant conclusions.The average research duraton in RCTs was 45 months.The total number of patients in 33 clinical RCTs was 2705 and the average number of patients recruited in each RCT was 82.Conclusion Chinese Journal of Hepatobiliary Surgery put emphasis on the strongest evidence and the most valuable RCT researches that have great significance in the field of domestic hepatobiliary surgery for clinical treatment and experimental research.
