Clinical characteristics of pregnant women with early and late onset preeclampsia and the matched control group (Control A and B).

<p>Values are shown as mean ± SD.</p><p>PE, preeclampsia; SBP, maximal systolic blood pressure; DBP, maximal diastolic blood pressure; Control A and Control B are gestational age-matched controls of normal pregnancies for ePE and lPE, respectively.</p>*<p><i>P</i><0.05, ePE versus Control A.</p>$<p><i>P</i><0.05, lPE versus Control B.</p><p>There were no significant differences in maternal age and delivery age between early and late-onset preeclampsia group and the matched control groups (<i>p</i>≥0.05). The blood pressure, systolic and diastolic blood pressures were significantly higher in preeclampsia groups than that in the matched control group (<i>p</i><0.05).
