Universal cervical‐length screening to prevent preterm birth in twin pregnancy: cost‐utility analysis

open access: yesUltrasound in Obstetrics &Gynecology, Volume 66, Issue 3, Page 290-297, September 2025.
ABSTRACT Objective The purpose of this cost‐utility analysis was to model the clinical and economic impact of three cervical‐length screening strategies among low‐risk twin pregnancies: two‐step universal screening (at 18–20 and 20–22 weeks), one‐step universal screening (at 18–20 weeks) and no screening.
