在临床试验和系统评价的搜索中，据说Google Scholar（GS）永远不应该单独使用，而是除了PubMed，科克伦和其他可信的信息来源之外。因此，我们进行了一项研究，以评估GS的覆盖范围，特别是对系统性综述中纳入的研究，并评估GS是否足够敏感，可以单独用于系统性综述。2009年发表在科克伦数据库Syst Rev或美国医学会杂志上的29篇系统评价中包含的所有原始研究都收集在金标准数据库中。对所有这些研究逐一检索GS，以评估仅检索GS即可识别的研究百分比。金标准数据库中纳入的所有738项原始研究均在GS中检索到（100%）。系统综述中纳入的研究的GS覆盖率为100%。如果29篇系统性综述的作者仅使用GS，则不会遗漏任何参考文献。随着研究选项的一些改进，以提高其精度，GS可以成为医学领域领先的书目数据库，并可以单独用于系统评价。
In searches for clinical trials and systematic reviews, it is said that Google Scholar (GS) should never be used in isolation, but in addition to PubMed, Cochrane, and other trusted sources of information. We therefore performed a study to assess the coverage of GS specifically for the studies included in systematic reviews and evaluate if GS was sensitive enough to be used alone for systematic reviews. All the original studies included in 29 systematic reviews published in the Cochrane Database Syst Rev or in the JAMA in 2009 were gathered in a gold standard database. GS was searched for all these studies one by one to assess the percentage of studies which could have been identified by searching only GS. All the 738 original studies included in the gold standard database were retrieved in GS (100%). The coverage of GS for the studies included in the systematic reviews is 100%. If the authors of the 29 systematic reviews had used only GS, no reference would have been missed. With some improvement in the research options, to increase its precision, GS could become the leading bibliographic database in medicine and could be used alone for systematic reviews.
