Maternal hematocrit models (percentage vs. maternal mass in kg for power law models, percentage vs. gestational age in weeks for all other models).

Maternal hematocrit models (percentage vs. maternal mass in kg for power law models, percentage vs. gestational age in weeks for all other models).产妇血细胞比容模型：幂律模型（power law models）的变量关联为血细胞比容百分比与以千克为单位的产妇体重；其余所有模型的变量关联则为血细胞比容百分比与以周为单位的孕龄。
