Distribution of TSH receptor autoantibody levels according to mild and severe Graves' orbitopathy, and comparison of the receiver operating characteristic analysis between two different TSH-receptor antibody assays. (a) Distribution of third-generation TBII assay. (b) Distribution of Mc4-TSI bioassay. (c) Comparing areas under the curve for each TRAb assay yielded that the predictive power of the third-generation TBII assay (AUC=0.817, 95% CI=0.732–0.902) was equivalent to that of the Mc4-TSI bioassay (AUC=0.868, 95% CI=0.803–0.934) in predicting severe patient disease outcome using the Delong method (P=0.203).
