Dynamic DBil and TBA Trajectories for Predicting Native Liver Survival in Biliary Atresia: A Multicenter Study with an Open-Access Online Tool.

Restricted cubic spline analyses confirmed that both biomarkers exhibited time-dependent, nonlinear associations with native liver survival.

Group-based trajectory modeling identified five clinically distinct trajectory subgroups for both DBil and TBA.

DBil trajectory groups demonstrated significant stratification of both native liver survival and overall survival (OS), whereas TBA trajectory groups stratified native liver survival alone.
