Efficiency of Disease and Disease Activity Diagnosis Models of Systemic Lupus Erythematosus Based on Protein Array Analysis

Figure 3

Efficiency and validation of the activity diagnosis model. (a) ROC of activity model in differentiating active SLE from inactive ones. (b) Calibration curve of activity model. (c) Nomogram of activity model with TNF RII, BLC, and MIP-1b. (d) Decision curve for the activity model in predicting active lupus. The red line represented activity model, grey line represented the assumption that all patients suffered active lupus, and black line represented the assumption that all patients had inactive lupus. (e) Clinical impact curve analysis diagram. Red line represented number of patients which were diagnosed with active lupus by our model at different threshold probability, and blue line represented number of patients with active lupus.
