Cerclage for sonographic short cervix in singleton gestations without prior spontaneous preterm birth: systematic review and meta-analysis of randomized controlled trials using individual patient-level data

What is it about?

In women with singleton gestation, without prior spontaneous PTB but with TVU CL <25mm in the second trimester, cerclage does not prevent preterm delivery or improve neonatal outcome. Cerclage, in singletons without prior spontaneous PTB, seems to be possible efficacious at lower CLs, such as <10mm, and when tocolytics or antibiotics were used as additional therapy, requiring further studies in these subgroups.
