Vaginal progesterone is as effective as cervical cerclage to prevent preterm birth in women with a singleton gestation, previous spontaneous preterm birth, and a short cervix: updated indirect comparison meta-analysis

The choice of treatment will depend on adverse events and cost-effectiveness of interventions and patient/physician's preferences.
