It compared the frequency of intraoperative adverse events between two groups: those at 24\u201325 weeks of gestation and at 26\u201327 weeks. Intraoperative adverse events were a classical incision, transplacental incision, difficulty in fetal extraction (explicitly mentioned in the surgical report), postpartum hemorrhage (\u2265500 <jats:styled-content style=\"fixed-case\">mL<\/jats:styled-content> of blood loss), and injury to internal organs. A composite outcome including at least one of these events enabled us to analyze the risk factors for intraoperative adverse events with univariate and multivariable analysis.

After adjustment for confounding factors, this group remained at significantly higher risk of intraoperative adverse events [adjusted odds ratio 5.04 (2.67\u20139.50)], even after stratification by
