Urine MPO concentration (A) and activity (B) from pregnant women who subsequently developed mild (n = 16) and severe (n = 14) preeclampsia (PE), and those that remained normotensive throughout pregnancy (HP; n = 57). No significant differences on MPO levels (P = 0.2) nor activity (P = 0.7) between HP (0.7 [0.04–0.9] ng/mL and 0.1 ± 0.05 U/L), mild PE (0.3 [0.04–1.7] ng/mL and 0.1 ± 0.04 U/L) and severe PE (0.1 [0.04–1.8] ng/mL and 0.1 ± 0.04 U/L), respectively. Data as median [minimum–maximum] or mean ± SD. Comparison of concentration between groups were by Kruskal-Wallis followed by Dunn’s or ANOVA 1-way followed by Tukey’s multiple comparisons test.
