Fig. 3From: Altered glycosylation profiles of serum IgG in Takayasu arteritisReceiver operating characteristic (ROC) curve analysis of SBA signal intensities from lectin microarrays. DeLong method was used to calculate the confidence intervals of ROC curve. The best predictive value of SBA signal intensity (1.4) and the corresponding specificity and sensitivity (71.1% and 73.8%, respectively) were shown. The area under the ROC curve (AUC) was 0.749 (95% CI: 0.693–0.806, p < 0.001)Back to article page
