ClinicalTrials.gov 是有关临床研究及其结果的信息库,连同专门的搜索工具,提供了了解临床研究企业的独特窗口,其中包括所有已启动、正在进行、已完成或终止的临床研究。研究人员越来越多地使用数据库中的信息来评估研究报告实践,或描述临床研究企业的特征。进行有效的分析需要了解数据库的功能和局限性(即内在因素)以及报告政策和数据库外部影响指定时间内 ClinicalTrials.gov 中研究类型的其他因素。本文讨论了研究人员在使用数据库进行研究时需要考虑的 10 个关键问题。
ClinicalTrials.gov, a repository of information about clinical studies and their results, together with specialised search tools, provides a unique window into the clinical research enterprise, which includes all initiated, ongoing, and completed or terminated clinical studies. Researchers are increasingly using information from the database to assess research reporting practices, or to characterise the clinical research enterprise. Conducting valid analyses requires an understanding of both the capabilities and limitations of the database (that is, intrinsic factors) as well as reporting policies and other factors external to the database that influence the types of studies in ClinicalTrials.gov in a specified time. This article discusses 10 key issues that researchers need to consider when using the database to conduct research.
