Area under ROC curve of the predicted probability of IgAN with “FIB + sIgA + Manifestation” combination from discriminant analysis. Area under the ROC curve for predicting immunoglobulin A nephropathy (IgAN) with the equation derived via discriminant analysis, which includes the “fibrinogen (FIB) + serum immunoglobulin A level (sIgA) + manifestation” combination. The state variable is IgAN.
