Development and external validation of a nomogram for predicting preterm birth at < 32 weeks in twin pregnancy

Abstract 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 asymptomatic women with twin pregnancies from January 2017 to December 2019 in two tertiary medical c...
