A comparison of the subjectively measured cervical dilatation and the dilatation measured objectively with a force-sensing instrument connected to metal dilators was made in two studies of cervical treatment prior to first trimester abortion. It was concluded that the subjective method is a sensitive and accurate method of measuring cervical dilatation but does not allow for comparison between different studies where an objective method of measurement should be used.
在两项关于孕早期人工流产前宫颈治疗的研究中,对主观测量的宫颈扩张程度与使用连接金属扩张器的力感应仪器客观测量的扩张程度进行了比较。得出的结论是,主观方法是一种测量宫颈扩张程度的灵敏且准确的方法,但不适合用于不同研究之间的比较,在这种情况下应使用客观测量方法。
