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.

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 full-text subset of EBSCO database from January 1st 1995 to December 31st 2004 were retrieved. Study selection: The literature indexed as 'Meta analysis in pt.' were searched and a random sample survey 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 were classified as type A, 57 as type B, and 28 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.收起
