Figure 2. Predictive accuracy of three models to assess the risk of type 2 diabetes. (A) Receiver operating characteristic curve of three models; (B) Decision curve analysis of three models; (C) Calibration curve of combination+lipids+galectin-3/adiponectin model. Model A: combination model (including the noninvasive factors BMI, WC, body fat and DBP) Model B: combination + lipids model (additionally including the invasive screening factors TC, TG and HDL-C) Model C: combination + lipids + galectin-3/adiponectin model (finally including galectin-3/adiponectin).
