目的：研究设计：一项回顾性队列研究，通过两个阶段的程序检查宫颈长度，经腹超声检查，然后经阴道超声检查宫颈长度，
OBJECTIVE: The aim of this study was to determine the value in the prediction of spontaneous preterm delivery of ultrasonographically measured cervical length measured between 14 and 24 weeks' gestation.STUDY DESIGN: A retrospective cohort study examined cervical length by means of a two-stage procedure, transabdominal ultrasonography followed by transvaginal ultrasonography ii cervical length was
