摘要
目的:调查网状Meta分析(network Meta-analysis,NMA)检索实施情况。方法:检索Pub Med、EMBASE.com、Web of Science和Cochrane library等数据库获取NMA,根据预先制定的纳入和排除标准纳入符合条件的NMA,提取检索实施方面的相关条目并输入Excel,采用STATA 12.0进行统计分析。结果:最终纳入391篇NMA,383篇NMA检索频率较高的数据库依次为Medline/Pub Med、EMBASE和CENTRAL,辅助检索频率较高的依次为追踪综述、检索在研试验、检索已经发表的Meta分析和追踪会议文献。检索最高的数据库组合为Medline/Pub Med+CENTRAL,而只有270篇NMA同时检索了Medline/Pub Med+EMBASE+CENTRAL,只有38.12%的NMA同时检索了数据库和已经发表的Meta分析。结论:调查显示目前NMA检索对NMA制作基本数据库检索不够,辅助检索措施尤其是对已发表Meta分析的检索有待加强。希望今后NMA撰写者同时检索基本数据库和已经发表的Meta分析,生产出高质量的NMA。
Objective： To analyze the current situation of retrieval of network Meta-analysis（ NMA）. Methods： Pub Med,EMBASE. com,Web of Science and Cochrane library were used to find potential NMA,NMA were select based on the inclusion and exclusion criteria. Data were extracted by Excel software and analyses were performed using STATA12. 0 software. Results： 391 NMA were included in this study. The most commonly retrieved databases were Medline / Pub Med,EMBASE,CENTRAL in 383 NMA,at the same time,review,ongoing trials,published Meta-analysis,conference were also searched in small number of NMA. Medline / Pub Med ＋ CENTRAL was the high frequency combined resources,only 270 NMA searched Medline / Pub Med ＋ EMBASE ＋ CENTRAL,at the same time,the database and published Meta-analysis have been searched in 38. 12% NMA. Conclusion： The databases have not covered basic databases in included NMA,especially published Meta-analysis need to be strengthened. At the same time,we should pay attention to published Meta-analysis and basic databases in the future.
