Review Meta Analysis Comparative StudyCerclage for short cervix on ultrasonography: meta-analysis of trials using individual patient-level data.
Preterm birth is the main cause of perinatal morbidity and mortality. A short cervical length on transvaginal ultrasonography predicts preterm birth. Our aim was to estimate by meta-analysis of randomized trials whether cerclage prevents preterm birth in women with a short cervical length. ⋯ Cerclage does not prevent preterm birth in all women with short cervical length on transvaginal ultrasonography. In the subgroup analysis of singleton gestations with short cervical length, especially those with a prior preterm birth, cerclage may reduce preterm birth, and a well-powered trial should be carried out in this group of patients. In contrast, in twins, cerclage was associated with a significantly higher incidence of preterm birth.

Review Meta Analysis Comparative StudyExpectant, medical, or surgical management of first-trimester miscarriage: a meta-analysis.
To quantify the relative benefits and harms of different management options for first-trimester miscarriage. ⋯ One additional success can be achieved among 3 women treated surgically rather than medically. Expectant management has had remarkably variable success rates across these studies, depending probably on the type of miscarriage. Greater standardization of outcomes should be a goal of future research.

Meta AnalysisContinuous labor support from labor attendant for primiparous women: a meta-analysis.
To evaluate the available literature on the effects of continuous labor support among primiparous women. ⋯ Labor support may have important positive effects on obstetric outcomes among young, disadvantaged women. Further studies on benefit relative to cost are needed before a broad-scale program is advocated.

Meta AnalysisEffect of epidural analgesia for labor on the cesarean delivery rate.
To use meta-analysis to evaluate the effect of epidural analgesia on the cesarean delivery rate. ⋯ The results of this meta-analysis strongly support an increase in cesarean delivery associated with epidural analgesia. Further research should evaluate the balance between analgesia associated with the use of epidurals, and postpartum morbidity and costs associated with cesarean deliveries.
