Women with intra-amniotic infection had higher amniotic fluid FcgammaBP than did those without intra-amniotic infection (with infection: median IQR 85.6 ng/mL, IQR 37.3–146.0 vs. without infection: median 12.6 ng/mL, IQR 9.1–20.3; Fig. 2a). This evidence concerns the gene FCGBP and chorioamnionitis.
