This paper outlines the protocol for a multicenter, prospective, observational cohort study in Shenzhen that aims to establish China's first dedicated online registry for patent ductus arteriosus in very preterm infants to investigate its epidemiology, develop a machine learning-based predictive model for hemodynamically significant cases, and support future biomarker research through a linked biobank.
