  • Status Survey on Systematic Review/Meta-analysis Related to Interventions Published in the Chinese Journals Entitled with Evidence-Based

    Objective To survey the current situation of the systematic review (SR)/ meta-analysis (MA) related to interventions published in the Chinese medical journals entitled with evidence-based. Methods According to the inclusion and exclusion criteria, the Journal of Evidence-Based Medicine (2001.1 to 2011.12), the Chinese Journal of Evidence-based Medicine (2001.1 to 2011.12), the Chinese Journal of Evidence Based Pediatrics (2006.1 to 2011.12) and the Chinese Journal of Evidence-Based Cardiovascular Medicine (2008.1 to 2011.12) were searched for SRs/MAs related to interventions. Two reviewers extracted data independently using predesigned a data extraction form, crosschecked data, and discussed to solve discrepancy. Excel software was used to for statistical analysis. Results A total of 487 SRs/MAs were included. 379 (77.82%) SRs/MAs were published in the Chinese Journal of Evidence-Based Medicine, 70 (14.38%) in the Journal of Evidence-Based Medicine, 30 (6.17%) in Chinese Journal of Evidence-Based Pediatrics, and 8 (1.63%) in the Chinese Journal of Evidence-Based Cardiovascular Medicine. The number of SRs/MAs published generally increased during 2001 to 2011. The number of author of SRs/MAs was 5±2, the number of studies that included randomized controlled trials (RCTs) of SRs/MAs varied from 1 to 129 (median: 8), involving 20 diseases. 83 (17.04%) SRs/MAs focused on neoplasms, 64 (17.04%) on diseases of the circulatory system, and 54 (11.09%) on diseases of the genitourinary system. 82.75% of the included 487 SRs/MAs assessed the methodological quality of included RCTs. 44 (9.03%) SRs/MAs mentioned the methods of quality assessment, without reporting the results. The Cochrane Collaboration’s tool for assessing risk of bias was the most frequently used for evaluation (314 SRs/MAs, 64.48%). Conclusion The number of SRs/MAs related to interventions published in the journals entitled with evidence-based is increasing generally and their topics are extensive. However, further studies should be improved in the aspects of selecting and applying the quality assessment criteria of randomized controlled trials.
