METHODS: Relevant meta-analysis were identifiedfrom Pub Med/Medline. The topics of meta-analyses were determined. Some topics(genetics, extragastric tumors) were analysed separately. Core journals publishing meta-analyses on Helicobacter pylori were ranked. The rate of citation of meta-analysis in major guidelines was calculated. RESULTS: Between 1992 and 2014, some 356 metaanalyses were published on Pub Med. These mainly appeared in core journals, but were also found in 128 other journals. Eradicating of the infection was the most addressed topic with 134 articles. Meta-analyses were rarely used in formulating statements and recommendations in the international guidelines. In other topics- genetics, extraintestinal manifestations-meta-analyses were rather overused. CONCLUSION: The implementation of meta-analysis in current guidelines is rather rare, while other topics benefit from many studies. A more extensive use of metaanalyses in evidence-based medicine is recommended in the future, otherwise their continuous proliferation will lose reason and scientific significance.展开更多
