Core Tip
Core Tip: This study included 340 children with biliary atresia who underwent liver transplantation. Seven key predictors of acute kidney injury (AKI) were screened out by least absolute shrinkage and selection operator algorithm, including pre-operative/post-operative creatinine (Cr), blood calcium and lactic acid levels during the anhepatic phase, gender, the amount of fresh frozen plasma infused during the operation, and post-operative aspartate aminotransferase level. Nine machine learning methods, including XGBoost, were used to construct the postoperative AKI prediction model based on other features after excluding postoperative Cr, and their prediction performance was compared. This study aims to assist clinicians in early intervention and improve the prognosis of children.
