研究设计的检索过滤器
我们的系统评价和随机对照临床试验 (randomised controlled trial, RCT) 的检索策略是由BMJ Knowledge Centre的信息专家在机构内部进行设计和检验。同样，观察性研究的策略和不良反应过滤器也是在机构内部设计而成的。设计这些策略旨在能检索到最可能符合我们方法学标准的研究。我们发现，在设计检索策略的过程中，有时不妨借鉴其他人的检索策略来开展我们的工作。我们所借鉴的策略以及其他相关工作可从 InterTASC 信息专家小组 (Information Specialists' Sub-Group, ISSG) 的网站上获得[1]。
注：以下显示的检索策略都是为 OVID 在线检索界面创建的。

上述例子是 BMJ Knowledge Centre使用的过滤器，当然也有其他可用的过滤器。有些数据库可能已经设置了供您选择使用的过滤器，因此这些过滤器可能对您也是有帮助的 (例如 PubMed) [2]。在检索策略设计和开展的过程中，如果您想获得进一步的建议和支持，请咨询您的图书馆或信息服务人员，他们应该能够提供帮助。
