a Receiver operating characteristics (ROC) curve comparing biochemical parameters in pediatric acute liver failure patients with poor outcomes. Peak INR > 5; sensitivity 69% and specificity 83%; {AUC 0.76, P < 0.03}. Lactate > 3.0 mmol/l; sensitivity 69% and specificity 100%; {AUC 0.87, P < 0.0001}. Peak ammonia > 115 μmol/l; sensitivity 76.9% and specificity 100%; {AUC 0.86, P < 0.001}. Peak Bilirubin > 77 mmol/l; sensitivity 84.6% and specificity 66.7%; {AUC 0.77, P < 0.02}. b Receiver operating characteristics (ROC) curve comparing scoring systems in pediatric acute liver failure patients with poor outcomes. Peak Peld-Meld > 29; sensitivity of 85% and specificity of 83%; {AUC 0.88, P < 0.001}. LIU score > 246; sensitivity of 84% and specificity of 83%; {AUC 0.83, P < 0.001}. UKELD score > 63; sensitivity 80% and specificity 83%; {AUC 0.89, P < 0.0001}
