LCN2 and preeclampsia: Our data revealed that (1) there was no correlation between maternal KIM-1 and NGAL levels in all three study groups (Figure 1A); (2) urine KIM-1 and NGAL levels were correlated in pregnant women complicated with CHT, r = 0.320, and in preeclampsia, r = 0.317, but not in normal pregnant women (Figure 1B); (3) urine and maternal NGAL levels were weakly correlated in normal pregnant women, r = 0.274, and in preeclampsia, r = 0.182, but not in women complicated with CHT (Figure 1C); and (4) there was no correlation between urine and maternal KIM-1 levels in all three study groups (Figure 1D).
