Fig. 1. HLI at ER for predicting HH utilizing AST and ALT. (A) ROC analysis utilizing AST for predicting the development of HH (AUC 0.737, 95% CI 0.643–0.830, red arrow: cut-off value AST>80 sensitivity 0.548 specificity 1–0.195=0.805). (B) ROC analysis utilizing ALT for predicting the development of HH (AUC 0.704, 95% CI 0.594–0.813, blue arrow: cut-off value ALT>80 sensitivity 0.452 specificity 1–0.071=0.929). ROC, receiver operating characteristics; AUC, area under the curve; AST, aspartate transaminase; ALT, alanine transaminase; CI, confidence interval; ER, emergency room; HH, hypoxic hepatitis; HLI, hypoxic liver injury.
