Quantitation of antibodies against TMABA-DH and α-SMA in sera from patients with KD or controls.

<p>(A) Data are presented as scattergrams for KD patients (KD) and for controls (Ctl). The difference between the reactivity of the anti-TMABA-DH antibody in KD patients and control patients is statistically significant (P<0.0005), while the reactivity of the anti-α-SMA antibody did not differ between the two groups (NS, not significant; <i>P</i>>0.45). Horizontal lines in the figure represent cut-off values for the anti-TMABADH antibody and the anti-α-SMA antibody, 0.043 and 0.007, respectively. Typical data from 5 independent measurements are shown. (B) ROC curve analyses of anti-TMABA-DH and anti—SMA antibody reactivity in (A) with AUC values of 0.84 and 0.47, respectively. Closed circles (designated by arrows) show the optimal cut-off points.
