IL2 and autoimmune hepatitis: When IL-2 was combined with the simplified AIH score for a combined score (sum of IL-2: < 10.8 μg/ml = 1, > 10.8 μg/ml = 0; simplified AIH score: ≤ 6 = 0, > 6 = 1), the predictive capacity in terms of the AUROC and specificity was even higher than with the individual parameters (Table 4, Fig. 2d).
