    The study by Kahraman et al. compares perinatal outcomes of single- versus double-suture cervical cerclage using a modified Wurm technique.

  • 2

    Three cerclage indications—history-indicated, ultrasound-indicated, and emergency—represent distinct clinical scenarios with varying cervical compromise.

  • 3

    Evidence suggests that double cerclage shows comparable outcomes in history-indicated cases, modest benefits in ultrasound-indicated, and significant benefits in emergency cases.

  • 4

    The authors' data indicate a significant difference in term delivery rates between single and double cerclage in emergency cases, contradicting their overall conclusion.

  • 5

    Concerns about the classification of cerclage indications in the dataset raise questions about the reliability of subgroup analyses and the study's conclusions.
