Figure 1 Receiver operating characteristic curve analysis of the alanine amino transaminase level at two years after living donor liver transplantation in the patients with a score of ≥ A1. The recommended cutoff value for diagnosing a score of ≥ A1 was set at 20 IU/L (sensitivity: 50.0%, specificity: 76.1%, area under the curve: 0.685 and 95%CI: 0.557-0.813).
