Premature rupture of the membranes was found to suppress rather than step up mortality, as was shown by examination of 919 newborns with birth weights of 2,500 g and less. The same conclusion was statistically secured for birth weights between 1,500 g and just below 2,000 g (p less than or equal to 0.05).-The above findings are likely to underscore results obtained by other authors who reported less occurrence of respiratory distress syndromes in premature newborns delivered after premature rupture of the membranes.-The frequency of premature ruptures tends to rise strongly along with declining birth weight, and similar correlations exist between perinatal mortality and birth weight. The authors, therefore, insist on the need for comparing only infants of one and the same birth weight (100 g-intervals), in order to forestall erroneous conclusions, otherwise inevitable.
对919名出生体重在2500克及以下的新生儿进行检查发现，胎膜早破会降低而非提高死亡率。对于出生体重在1500克至略低于2000克之间的情况，同样的结论在统计学上得到了证实（p小于或等于0.05）。上述发现可能会进一步强调其他作者所获得的结果，这些作者报告称，胎膜早破后分娩的早产新生儿呼吸窘迫综合征的发生率较低。胎膜早破的频率往往随着出生体重的下降而大幅上升，围产期死亡率与出生体重之间也存在类似的相关性。因此，作者坚持认为，为了避免不可避免的错误结论，有必要仅对出生体重相同（100克间隔）的婴儿进行比较。
