本文介绍了针对妊娠和分娩护理领域，如何制定和更新随机对照试验的系统评价，以帮助决策者、从业者和用户获取可靠信息。
People providing health care tend to turn to review articles rather than reports of primary research when seeking information to guide their practices. For this reason, the process of reviewing the results of primary research must respect scientific principles. Reviews must be kept up to date and disseminated in appropriate ways to the people who make decisions about health care, including policy makers, practitioners, and users of the health services. This article describes the methods developed and used in an attempt to address these challenges for care during pregnancy and childbirth.
