Objective:

To identify risk factors for preterm birth and extended gestation after cervical cerclage (CC) in women with cervical insufficiency, emphasizing the significance of developing a predictive model for postoperative fetal retention time.

Key Findings:

• Cervical insufficiency is a significant risk factor for preterm birth, highlighting the need for targeted interventions.
• Emergency CC can prolong gestational age and improve neonatal survival rates, suggesting its critical role in management.
• Variability in defining preterm birth thresholds may influence study outcomes, necessitating standardized definitions.

Interpretation:

The study highlights the need for personalized and dynamic determination of preterm birth thresholds based on local delivery timing data and fetal survival outcomes, with implications for clinical practice.

Limitations:

• Cervical insufficiency diagnosis lacks universally standardized criteria, which may introduce variability.
• Inter-center variability in diagnostic thresholds may affect case classification and introduce biases inherent in retrospective studies.

Conclusion:

The study aims to provide a quantitative framework for CC decision-making and postoperative risk stratification, underscoring the importance of the predictive model developed.
