生物医学科研人员进行Meta分析时,检索数据库的选择直接影响纳入的研究是否全面、客观、真实,并最终影响系统评价的有效性。目前,中文论文数量位列世界第二,仅次于美国,但国内外研究人员在做系统评价时很少检索中文医学数据库。文章选取了4种Meta分析主题,共计8篇论文,其中4篇检索了中文数据库,4篇没有检索中文数据库,对比分析了中文数据库是否对Meta分析结果产生影响。通过分析Cochrane Library数据库中的所有文献,总结了目前Meta分析检索中文数据库的现状。
When biomedical researchers conduct meta-analyzes, the choice of search database has a direct impact on the comprehensiveness, objectivity and truth of the study being studied and ultimately the effectiveness of the systematic review. Currently, the number of Chinese papers ranks second in the world after the United States, but researchers at home and abroad rarely search Chinese medical databases for systematic reviews. The article selected four Meta-analysis themes, a total of eight papers, of which 4 Chinese database search, 4 did not retrieve the Chinese database, comparative analysis of the Chinese database whether Meta analysis results. By analyzing all the documents in the Cochrane Library database, the current status of searching Chinese databases by Meta-analysis was summarized.
