The gestational ages of 66 neonates delivered after positive contraction stress tests (CSTs) were estimated by means of the Dubowitz score. Forty-three (65%) of these infants had birth weights below the 10th percentile according to their gestational age. At the beginning of the study 40% of the infants were found to be growth-retarded, but as experience with antenatal fetal heart rate monitoring increased the CSTs were interpreted more accurately. This led to an increase in the incidence of IUGR in infants born after a positive CST to 82%, a predictive value which means that the test compares favourably with other methods of diagnosing the small-for-dates fetus.
对66例宫缩应激试验（CST）阳性后分娩的新生儿，采用杜波维茨评分法估算其胎龄。根据胎龄，这些婴儿中有43例（65%）出生体重低于第10百分位数。研究开始时，发现40%的婴儿生长迟缓，但随着产前胎儿心率监测经验的增加，对CST的解读更加准确。这使得CST阳性后出生的婴儿中，宫内生长受限（IUGR）的发生率增至82%，这一预测价值表明该试验与诊断小于胎龄儿的其他方法相比具有优势。
