Participant characteristics. Table shows demographics and cardiovascular risk factor information of the participants, comparing the 4 groups of women. P-values were generated using Fisher’s Exact and Kruskal-Wallis ANOVA by Ranks Tests.

^*Results from Fisher’s Exact test between two groups with history of Preeclampsia only

Significant p-value shows that within each pregnancy group, mean SBP was greater in women with current hypertension than without hypertension (P<0.02). Non-significant p-values indicate that none of the four groups differed on those characteristics.
