Correlation between neonatal outcomes of twins depends on the outcome : Secondary analysis of twelve randomised controlled trials

2018

ObjectiveTo estimate the magnitude of the correlation between neonatal outcomes of twins and demonstrate how this information can be used in the design of randomised controlled trials (RCTs) in women with twin pregnancies.DesignSecondary analysis of data from 12 RCTs.SettingObstetric care in multiple countries, 2004-2012.Population or sample4504 twin pairs born to women who participated in RCTs to assess treatments given during pregnancy.MethodsIntraclass correlation coefficients (ICCs) were estimated using log-binomial and linear models.Main outcome measuresPerinatal death, respiratory distress syndrome, bronchopulmonary dysplasia, intraventricular haemorrhage, necrotising enterocolitis, s…

Effectiveness of progestogens to improve perinatal outcome in twin pregnancies : an individual participant data meta-analysis

2015

Background In twin pregnancies, the rates of adverse perinatal outcome and subsequent long-term morbidity are substantial, and mainly result from preterm birth (PTB). Objectives To assess the effectiveness of progestogen treatment in the prevention of neonatal morbidity or PTB in twin pregnancies using individual participant data meta-analysis (IPDMA). Search strategy We searched international scientific databases, trial registration websites, and references of identified articles. Selection criteria Randomised clinical trials (RCTs) of 17–hydroxyprogesterone caproate (17Pc) or vaginally administered natural progesterone, compared with placebo or no treatment. Data collection and analysis I…
