Local cervical treatment for preinvasive cervical disease such as cervical intraepithelial neoplasia (CIN) has been associated with an increased risk of preterm birth, perinatal morbidity, and mortality in a later pregnancy. This meta-analysis aimed to investigate the impact of treatment for cervical preinvasive and early invasive disease on obstetric outcomes and to see how this risk could be modified by the cone depth and comparison group.
