Fetal weight estimation was performed in 58 women with preterm premature rupture of the membranes within 4 days of delivery. Of twelve formulas evaluated, only two met the requirements for clinical use (i.e., they had a small mean percent error and a high correlation). However, both had high random error, which may be attributable to the very low birth weights studied.
在分娩前4天内胎膜早破的58名女性中进行了胎儿体重估计。在评估的12个公式中，只有两个符合临床使用要求（即平均误差百分比小且相关性高）。然而，这两个公式都有很高的随机误差，这可能归因于所研究的极低出生体重。
