A study was undertaken to assess the value of symphysis-fundus measurement as a screening procedure for intrauterine growth retardation. The reproducibility of this measurement was investigated in two groups of six patients, each measured six times by six different observers. The intraobserver coefficient of variation was 4.6% and the interobserver coefficient of variation 6.4%. There was no evidence that experience aided consistency. A chart of symphysis-fundus measurements derived from Cardiff data was found to be similar to others previously published, and one measurement below the 10th centile identified 64% of pregnancies in which the eventual birth weight was below the 10th centile for gestational age. Symphysis-fundus measurement is a useful screening test; one chart could be used for any Caucasian population and should be incorporated into the maternity services "co-operation card."
开展了一项研究，以评估耻骨联合-宫底测量作为宫内生长迟缓筛查方法的价值。在两组各6名患者中对该测量的可重复性进行了研究，每组由6名不同的观察者对每位患者测量6次。观察者内变异系数为4.6%，观察者间变异系数为6.4%。没有证据表明经验有助于提高一致性。发现源自加的夫数据的耻骨联合-宫底测量图表与之前发表的其他图表相似，一次测量值低于第10百分位数可识别出64%最终出生体重低于胎龄第10百分位数的妊娠。耻骨联合-宫底测量是一项有用的筛查试验；一张图表可用于任何白种人群体，应纳入产科服务的“合作卡”中。
