To produce population-based, gender- and gestational-age-specific centile curves for placental weight.
Population study.
Medical Birth Registry of Norway.
All singleton live births in Norway from 1 January 1999 to 31 December 2002.
In a cohort of children born in Norway, placental weights and the ratio of the birthweight to the placental weight were analysed to produce percentile curves.
Placental weight, birthweight-to-placental weight ratio.
Tables and figures are presented for placental percentiles curves according to gestational age and gender. Also, tables and figures are presented for the ratio of birthweight to placental weight. CONCLUSIONS To our knowledge, this is the first time that population percentile curves have been produced for placental weights and hence for the ratio of birthweight to placental weight. These percentile curves may act as a reference for other populations as well until population-specific curves can be produced.
生成基于人群、按性别和胎龄划分的胎盘重量百分位数曲线。
人群研究。
挪威医学出生登记处。
1999年1月1日至2002年12月31日在挪威出生的所有单胎活产儿。
在一组挪威出生的儿童中，分析胎盘重量以及出生体重与胎盘重量的比值，以生成百分位数曲线。
胎盘重量、出生体重与胎盘重量的比值。
列出了根据胎龄和性别的胎盘百分位数曲线的表格和图表。此外，还列出了出生体重与胎盘重量比值的表格和图表。
据我们所知，这是首次生成基于人群的胎盘重量以及出生体重与胎盘重量比值的百分位数曲线。在能够生成特定人群的曲线之前，这些百分位数曲线也可为其他人群提供参考。
