Figure 3. Receiver Operating Characteristic (ROC) Curves and Area Under the Curves (AUC) of (Combined) Diagnostic Tests for Pemphigoid Using Multivariable Logistic Regression Modeling.

Figure 3.

The overlap between model DIF + IIF SSS and model DIF + IIF SSS + NC16A ELISA indicates no statistically significant difference in AUC and no diagnostic value added by NC16A ELISA to the DIF and IIF SSS tests. DIF indicates direct immunofluorescence microscopy; ELISA, enzyme-linked immunosorbent assay; IIF SSS, indirect immunofluorescence on human salt-split skin substrate.
