Cervical pessary for preterm-birth prevention among pregnant women with a short cervix: A prospective cohort study

The success birth rate (delivered from 34 weeks or later) was high when placing the cervical pessary in pregnant women with a short cervical length <25 mm. The history of preterm birth was associated with the rate of delivery before 34 weeks of gestation. The results of this cohort study underscore the need for further investigation in large-scale advanced studies to establish a higher level of evidence and ensure the best outcomes for maternal and child health.
