Subgroup analysis showed that in twin pregnancies with cervical dilatation or cervical length less than 10\u2009mm, the cerclage group had significantly higher gestational age at delivery (31.3\u2009\u00b1\u20094.6 vs 23.4\u2009\u00b1\u20094.3\u2009weeks, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001) and a higher neonatal survival rate (123 [85.4%] vs 4 [9.1%], <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001) than the no cerclage group, but in twins when cervical length was 10\u201315\u2009mm, the two measures were similar between the two groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Transvaginal cerclage may provide benefits for twins when cervical dilatation or cervical length is less than 10\u2009mm, but its efficacy might not extend to twins when the cervical length is 10\u201315\u2009mm.
