New Nomogram Enhances Preterm Birth Risk Assessment – AJOG MFM

American Journal of Obstetrics and Gynecology MFM – AJOG MFM shared a post on LinkedIn:

“Preterm Birth

A newly developed and externally validated multivariable nomogram helps estimate individualized, time-dependent risk in singleton pregnancies with cervical length ≤25 mm — moving beyond cervical length alone.

Key predictors

  • Prior preterm birth
  • Cervical length
  • Gestational age at diagnosis

Strong performance across training and external validation cohorts

  • Good discrimination (AUC up to 0.77)
  • Excellent calibration
  • Demonstrated clinical utility across risk thresholds

Why it matters

This simple, practical tool supports personalized counseling and risk stratification — helping clinicians tailor management for patients at highest risk.
