摘　　要：目的:以有效检索策略为基础的Meta分析,所做的临床决策会对患者产生积极的疗效。文章调查了Meta分析报道检索策略效果证据的范畴。资料来源:对1995-01-01/2004-12-3110年间,EBSCO数据库MED-LINE全文子集进行检索。资料选择:对MEDLINE全文子集中,标引“Meta分析”为出版物类型的论文,进行随机抽样调查(n=100)。资料提炼:以3种方法对这些论文进行分类:论文A类:既足够详细地报道了检索策略(以便于它可能被重复利用),又提供了检索策略效果的证据;论文B类:足够详细地报道了检索策略,但没有提供检索策略效果的证据;论文C类:既没有足够详细地报道检索策略,也没有提供检索策略效果的证据。被分为A类的论文根据所报道的证据水平进一步再分类。资料综合:在最后分析的93篇论文样本中,8篇(8.6%)被分为A类,57(61.3%)篇被分为B类,28篇(30.1%)被分为C类。A类中的论文报道了先前有效的、公开发表了的或者基于专家意见的检索策略。结论:专家评审标准一定要力争得到进一步发展,那就要求Meta分析的作者,对他们检索策略的效果证据要加以报道。OBJECTIVE： Clinical decisions base on the Meta analysis that is based on an effective retrieval strategy may have positive consequences for patients. The aim of study was to investigate the extent which the authors of the Meta-analysis report proof of their retrieval strategies＇ effectiveness. DATA SOUCES： The Medline lull-text subset of EBSCO database from January 1^st 1995 to December 31^nd 2004 sere retrieved. STUDY SELECTION： The literature indexed as ＂Meta analysis in pt.＂ were searched and a random sample survey （n=100） was performed from the full-text subset of Medline database. DATA EXTRACTION： These articles were classified by three ways： Articles of type A reported both a retrieval strategy in sufficient detail such that it could be repeated and with evidence of the strategy＇s effectiveness, those of type B reported a retrieval strategy in sufficient detail but not with evidence of the strategy＇s effectiveness, and those of type 3 neither reported a strategy in detail nor evidence of the strategy＇s effectiveness. Those classified as type A were further classified according to the level of evidence reported. DATA SYNTHESIS： Of the 93 articles in the final analysis, 8 （8.6%） were classified as type A, 57 （61.3%） as type B, and 28 （30.1%） as type C, The articles in type A reported a previously validated search, a published strategy, or strategy Based on expert opinion. CONCLUSION： The standards of peer-review must be developed that require authors of meta-analyses to report evidence for the effectiveness about their retrieval strategies.
