Is cerclage safe and effective in preventing preterm birth in women presenting early in pregnancy with cervical dilatation?
Bibliographic record
Abstract
### What you need to know Preterm birth and its complications account for nearly one million neonatal deaths each year globally.1 Women who present with a dilated cervix in the second trimester are at increased risk of pregnancy loss and preterm birth (fig 1). They generally have no or minimal preceding symptoms such as change in discharge or mild abdominal pain and are detected to have a dilated cervix on examination. Cervical dilatation may also be detected in the anomaly scan. Fig 1 Premature cervical dilatation and exposed unruptured fetal membranes International guidelines from the US, UK, and Canada suggest considering emergency cervical cerclage, or rescue cerclage, to prevent preterm birth in women presenting with cervical dilatation and exposed fetal membranes between 16 and 28 weeks of gestation if there are no signs of bleeding, infection, or uterine activity (see box 1).2 Box 1 ### NICE guidelines for management of preterm labour and birth (NG25)2 #### Women with a closed cervixRETURN TO TEXT

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
