Cervical length under 26 mm strongly predicts preterm birth: Study
A cohort study of 70 pregnant women found that cervical length is a strong predictor of preterm labour. Preterm births occurred in 30% of participants, mostly when cervical length measured under 26 mm at 20-24 weeks. Cervical length assessment showed high sensitivity and specificity, supporting its routine use for early detection and prevention of preterm birth.
