目的：本研究的目的是评估不和谐双胞胎的新生儿死亡率，根据较小的双胞胎的出生体重进行分类。研究设计：我们比较了三组不和谐双胞胎的新生儿死亡率(>；25%)，以较小的双胞胎的出生体重为第50%来区分。结果：在10,683对双胞胎中，三组的比例分别为62.4%，32.9%和4.7%。在双胞胎中体重较小的双胞胎中，新生儿死亡率显著较高。
Objective: The purpose of this study was to evaluate neonatal mortality rates among discordant twins, classified according to the birth weight of the smaller twin.Study design: We compared neonatal mortality rates among three groups of discordant twins (>25%), distinguished by the birth weight of the smaller twin being 50th percentile.Results: Among the 10,683 pairs of twins who were studied, the respective proportions of the three groups were 62.4%, 32.9%, and 4.7%. The neonatal mortality rate was significantly higher among pairs in which the smaller twin weighed
