Make a neonatal jaundiced nomogram on Chinese jaundice data by joinning the major neonate centers all around China.

This was a multi-centre prospective study. All infants included were born in 8 hospitals in the southern, eastern, northern, western and central regions of mainland China in 2019. A total of 20839 transcutaneous bilirubin(TCB) measurements were performed with 2977 neonates at designated time points. The mean NTL exposure during pregnancy was respectively calculated based on each participant's residential address over the study course. The primary outcome was whether the neonate was diagnosed with hyperbilirubinemia within the first seven days of life. The effect of maternal nocturnal light exposure on neonate jaundice analyzed with lasso regression and random forest machine learning methods.
