Objective To survey the important characteristics, such as the number of time cited, methodological and reporting quality of the systematic review/meta-analysis (SR/MA) of animal studies published in Chinese journals. Methods The CNKI and WanFang Data databases were searched for SR/MA of animal studies published in Chinese journals from inception to March 2014. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted basic characteristic and methodology characteristics of included studies. And then a descriptive analysis was conducted. Results A total of 18 studies published in 13 different journals were included. 77.8% studies were not been cited, 44.4% did not report the types of including studies. Besides, there were some certain weaknesses in the methodological quality, for example, over 60% studies did not assess the qualities and publication bias of the including studies, 22.2% SRs/MAs only searched Chinese databases, over 80% studies did not provide flow chart etc. Conclusion The number of SRs/MAs of animal studies published in Chinese journals is small and the number of times cited is low, and the methodological and reporting quality is poor. So, focusing on improving the quality of SRs/MAs is urgently needed in order to increase the value of these studies.
