A dynamic nomogram calculator based on prenatal and perinatal variables
A risk prediction model based on nomograms was used to predict the neonatal mortality rate among peri-viable infants of gestational age 22 weeks to 25 weeks. To identify the key predictors for the prognostic model, multivariable logistic and Cox regression analyses were performed on the 3-, 7- and 28-day mortality risk among peri-viable infants.
