Many of the practices carried out during antenatal care improve the well-being of mother or baby and reduce the burden of adverse perinatal outcome. Other practices have either not been evaluated or have been shown to be ineffective. Evidence from randomized clinical trials provides the best evidence about the effectiveness of these practices.
许多产前护理措施可改善母亲或婴儿的健康状况，并减轻围产期不良结局的负担。其他措施要么未经过评估，要么已被证明无效。随机临床试验的证据为这些措施的有效性提供了最佳证据。
