 Two studies were in favor of the pessary as a preventive method, one study was contrary to the method and another two showed no statistically significant difference. The meta-analysis showed no statistical difference with the use of a cervical pessary in the reduction of births < 37 (odds ratio [OR]: 0.63; confidence interval [95% CI]: 0.38-1.06) and < 34 weeks (OR: 0.74; 95% CI: 0.35-1.57) CONCLUSION:  The pooled data available to date seems to show a lack of efficacy of the cervical pessary in the prevention of preterm birth, although the heterogeneity of the studies made comparisons more difficult.
