Patient characteristics (mean + SD and (range)) for age, pre-pregnancy BMI, maternal calcium, 25- OH vitamin D, 1,25-(OH)₂ vitamin D levels in serum, systolic (SBP) and diastolic (DBP) blood pressure on admission to the hospital, as well as child length, weight, and BMI standard deviatio

In patients with preeclampsia, maternal 25-OH vitamin D levels are significantly lower than in healthy controls. * differs from healthy controls (*P<0.05, ** P<0.01) #blood pressure obtained on admission to hospital was below the criterion for preeclampsia in one patient, despite preeclampsia with proteinuria and elevated blood pressure readings before and after admission.子痫前期（preeclampsia）患者的母体25-羟基维生素D（25-OH vitamin D）水平显著低于健康对照组，该差异具有统计学意义（*P<0.05，**P<0.01）。【注】1名患者入院时测得的血压未达到子痫前期的诊断标准，但该患者入院前后均存在蛋白尿伴血压升高的子痫前期表现。
