目的：我们试图根据宫颈长度 (CL) >= 25 mm 的连续体来评估妊娠结局。 研究设计：我们对一项随机环扎试验进行了有计划的二次分析，试验对象为 17(0)-34(6/7) 周自发性早产的妇女。对保持 CL >= 25 mm 的女性的结果进行了分析。 CLs = 25 mm 且出生胎龄为零的女性 ( P = .15)。在 16(0/7)-22(6/7) 周之间测量的 = 25 毫米并不能预测既往自发性早产的妇女的妊娠长度。
OBJECTIVE: We sought to assess pregnancy outcome along a continuum of cervical lengths (CLs) >= 25 mm.STUDY DESIGN: We conducted planned secondary analysis of a randomized cerclage trial of women with prior spontaneous preterm birth 17(0)-34(6/7) weeks. Outcomes of women who maintained CLs >= 25 mm were analyzed. Women with CLs = 25 mm and birth gestational age was null ( P = .15). In the = 25 mm measured between 16(0/7)-22(6/7) weeks does not predict gestational length in women with prior spontaneous preterm birth.
