Amniotic fluid concentrations of retinol-binding protein 4 (RBP4) among women with spontaneous preterm labor (PTL) and intra-amniotic infection/inflammation (IAI) who delivered within 72 h of amniocentesis and have placental histopathologic diagnosis: The median amniotic fluid RBP4 concentration was significantly higher in patients with IAI and histologic chorioamnionitis than in women with IAI without histologic chorioamnionitis [1901.0 ng/mL, interquartile range (IQR) 1107.3-2492.0 vs. 968.2 ng/mL, IQR 634.7-1396.7; p=0.01]. The black lines represent the median and IQR.
