  1. A comparison of maternal and pregnancy characteristics between the two groups: pregnant women that have developed preeclampsia (PE) and pregnant women with uncomplicated pregnancies (control). P-values were calculated using Fisher exact test for categorical variables, and using Mann-Whitney U test for continuous variables.
