Amniocentesis-to-delivery interval in accordance with histologic status of the extra-placental membranes.

<p>Amniocentesis-to-delivery interval is shown according to histologic status of the extra-placental membranes (i.e., inflammation-free, chorio-deciduitis only, and chorio-deciduitis with amnionitis) in patients with PTL (median, range; 20.6 hours [0.01–1794.8 hours] vs. 113.9 hours [0.10–1093.1 hours] vs. 654.5 hours [312.2–718.2 hours]) and preterm-PROM (median, range; 42.9 hours [0.01–1267.2 hours] vs. 95.2 hours [0.01–1833.9 hours] vs. 131.3 hours [90.2–655.0 hours]). P-values and Spearman rank correlation coefficients are shown.
