Rennert KN, Breuking S, Schuit E, et al. - Researchers conducted this post hoc analysis of a randomized clinical trial measuring transvaginal cervical length in women with cessation of contractions 48h after admission for threatened preterm labor in order to determine the correlation between preterm birth and cervical length after arrested preterm labor in high‐risk women. The analysis was performed including a total of 164 women. Findings revealed lower risk of preterm birth before 34 weeks when cervical length increased between admission for threatened preterm labor and 48 hours later when contractions have ceased, compared with when cervical length did not change or decreased.
