ROC curve analysis for predicting repeated IVIG resistance
ROC curves were used to calculate the AUC and predictive values of each coagulation parameter (Table 3 and Figure 2B). The AUC of ATIII for predicting repeated-KD patients was 0.753. In repeated-KD patients, the cutoff value of ATIII was 68.5%, which yielded a sensitivity of 71%, specificity of 55% for predicting repeated-IVIG resistance.
