一个统一的协议是必不可少的，以确保在多中心研究中进行的胎儿超声测量是准确的和可重复的。本文介绍了用于在INTERGROWTH-21项目的纵向胎儿生长部分进行二维超声测量的方法。这些标准化方法应尽量减少与不同研究中心合并数据相关的系统误差。它们为今后开展类似的研究提供了一个模式。
A unified protocol is essential to ensure that fetal ultrasound measurements taken in multicentre research studies are accurate and reproducible. This paper describes the methodology used to take two-dimensional, ultrasound measurements in the longitudinal, fetal growth component of the INTERGROWTH-21st Project. These standardised methods should minimise the systematic errors associated with pooling data from different study sites. They represent a model for carrying out similar research studies in the future.
