^⁎One-way analysis of variance (ANOVA).

^†One-way ANOVA followed by t-test showed significant differences between the comparisons of all groups (preeclampsia versus term, P < 0.0001; preeclampsia versus preterm, P = 0.033; preterm versus term P = 0.0023).

^‡One-way ANOVA followed by t-test showed significant differences between preeclampsia versus term and preeclampsia versus preterm.

^§Kruskal-Wallis test.
