FCGBP and infection: Differences in the concentrations of FcgammaBP were identified among the subgroups of women with intra-amniotic infection, sterile intra-amniotic inflammation, and negative amniotic fluid (infection: median 139.7 ng/mL, IQR 74.2–205.3; sterile: median 54.2 ng/mL, IQR: 44.8–127.0; negative: median 19.7 ng/mL, IQR: 15.9–23.6; Fig. 1b) in the crude analysis and after the adjustment for gestational age at sampling (both p-values < 0.0001).
