There was no significant increase in MPO, (6.72 ng/ml [2.20–13.13], 7.09 ng/ml [2.74–17.24], 8.33 ng/ml [5.70–14.20]; P = 0.14), MMP-8 (1075.62 pg/ml ± 88.24, 1053.74 pg/ml ± 54.05, 1140.64 pg/ml ± 87.08; P = 0.82) or IL-8 (9.32 pg/ml [2.18–29.85], 13.49 pg/ml [3.66–46.66], and 24.63 pg/ml [5.37–71.20]; P = 0.13) across gestation in preeclampsia cases (Fig. 5c–e). Here, CXCL8 is linked to preeclampsia.
