Conclusions
Plasma PZ and ZPI are significantly decreased in pregnant women with FGR, which can be used for pregnant women's FGR screening.
Material and methods
In this study, the number of pregnant women with FGR, healthy pregnant women (Healthy Control, HC), and childbearing-age women without pregnancy (Blank Control, BC) is 79, 79, and 60, respectively; their plasma PZ and ZPI levels in each group are determined by ELISAs. Then, the correlations between these indices and FGR were assessed using Spearman analysis. Moreover, these indices' diagnostic values for FGR are evaluated using the receiver operating characteristics (ROC) curves.

Results
The plasma levels of PZ and ZPI are significantly decreased in the HC and FGR groups compared against the BC group (P < 0.001), whilst the levels of PZ and ZPI in the FGR groups are lower than those in the HC group (P < 0.01) notably. PZ plasma concentration has positive relationship with ZPI concentrations in the HC and FGR groups. The combination of PZ and ZPI, with the Area under the Curve (AUC) 0.92 (95% CI = 0.88-0.96), the sensitivity 0.82, and the specificity 0.88, outperforms everyone. Conclusions: Plasma PZ and ZPI are significantly decreased in pregnant women with FGR, which can be used for pregnant women's FGR screening.
