ROC and AUC of the prediction models for IVIG-resistance. The new predictive model for IVIG-resistance showed an AUC of 0.74, Compared with previous IVIG-resistant scoring systems, the new model presented a higher AUC value than the Kobayashi (AUC = 0.68), Egami (AUC = 0.65), Sano (AUC = 0.55) and Yang (AUC = 0.67) methods. ROC, receiver-operator characteristic curves; AUC, area under the curve.
