Proportion Chorion ( = chorion (µm)/choriodecidua (µm)) by Clinical Group and Membrane Location, where “rupture” is membrane rupture site and “distant” is distal site sampled.

Value shown represents the proportion of mean chorion thickness as it relates to total mean choriodecidua thickness with standard errors. Each pPPROM = Preterm, premature rupture of membranes (subjects between 24 and 34 weeks following confirmation of rupture of membranes by physical exam).Preterm = subjects between 24 and 34 weeks of gestation with and without exposure to labor.Term = subjects between 37 and 41 weeks with and without exposure to labor.Rupture = sample of membrane collected at site of rupture.Distant = sample of membrane collected from an area distant to rupture site, most commonly near the placenta.本次展示的数值为绒毛膜平均厚度占绒毛膜-蜕膜总平均厚度的比例，附带标准误。 pPPROM（早产胎膜早破，preterm premature rupture of membranes）：指经体格检查确认胎膜破裂后，孕周介于24至34周的受试者。 早产组（Preterm）：孕周介于24至34周，无论是否存在临产暴露史的受试者。 足月组（Term）：孕周介于37至41周，无论是否存在临产暴露史的受试者。 破裂位点样本（Rupture）：在胎膜破裂位点采集的胎膜组织样本。 远位样本（Distant）：在距离破裂位点较远的区域（最常见为胎盘附近）采集的胎膜组织样本。
