nomogram model for predicting preterm birth and verify its application value. Methods: Data …

Purpose This study aimed to develop two-stage nomogram models to predict individual risk
of preterm birth at< 34 weeks of gestation in twin pregnancies by incorporating clinical …

The purpose of this study was to develop a dynamic model to predict the risk of spontaneous
preterm birth at< 32 weeks in twin pregnancy. A retrospective clinical study of consecutively …

Background: Twin pregnancies are associated with an increased risk of adverse maternal
and neonatal outcomes, mainly owing to prematurity. Few studies have evaluated the risk …

In twin pregnancies, which are at high risk of preterm birth, it is not known if maternal clinical
characteristics pose additional risks. We undertook a systematic review to assess the risk of …

model for spontaneous preterm birth (sPTB) in twin pregnancies. Methods This a …

In women with twin pregnancies biomarkers are not used to predict preterm birth in clinical
practice. This systematic review assessed the risk of both spontaneous and iatrogenic …
