Serum Cytokines Th1, Th2, and Th17 Expression Profiling in Active Lupus Nephritis-IV: From a Southern Chinese Han Population

Figure 4

Receiver operating characteristics (ROC) curve of serum cytokines for differential diagnosis of LN-IV from LN-III and LN-V. The area under ROC curve of the serum cytokines levels IL-18, IL-17A, IL-18/IL-4, and IL-17A/IL-4 ratios was calculated and the accuracy of using these serum cytokines levels in the diagnosis of LN-IV from LN-III and LN-V was analyzed (data in Table 3).
