Progression characteristics of biliary atresia during the waiting period for liver transplantation: a single-center observational study

This study provides unprecedented quantification of the rapid natural progression of BA cirrhosis, revealing a critical 3 month window of clinical deterioration. The dynamic changes in routinely available laboratory markers, particularly neutrophil percentage and ammonia, offer clinically accessible indicators for risk stratification and monitoring, forming a practical "dashboard" for managing BA patients awaiting transplantation in resource-varied settings.
