Clinical characteristics and pregnancy outcomes of study subjects.

Values are given as mean ± standard deviation, n (%) or median (range).MIR, maternal inflammatory response; FIR, fetal inflammatory response; BMI, body mass index; pPROM, preterm premature rupture of membranes.*Active labor was defined as cervical dilatation of 3 cm or more in the presence of regular uterine contractions.aComparison between groups with no placental inflammation and MIR;bComparison between groups with MIR and FIR;cComparison between groups with no placental inflammation and FIR;dComparison among groups with no placental inflammation, MIR and FIR.Clinical characteristics and pregnancy outcomes of study subjects.

统计数据以均值±标准差、例数（百分比）或中位数（范围）形式呈现。MIR代表母体炎症反应（maternal inflammatory response），FIR代表胎儿炎症反应（fetal inflammatory response），BMI代表体质量指数（body mass index），pPROM代表早产胎膜早破（preterm premature rupture of membranes）。*活跃产程定义为存在规律宫缩时宫颈扩张≥3 cm。a：无胎盘炎症组与MIR组的组间比较；b：MIR组与FIR组的组间比较；c：无胎盘炎症组与FIR组的组间比较；d：无胎盘炎症组、MIR组与FIR组的组间多重比较。本研究受试者的临床特征与妊娠结局。
