Identification and validation of serum amino acids as diagnostic biomarkers for diabetic peripheral neuropathy

Figure 3 Receiver operating characteristic area under the curve for the specificity and sensitivity of the predictive model in the training cohort and validation cohort. A: Performance of the prediction model for discriminating diabetic peripheral neuropathy (DPN) patients from type 2 diabetes mellitus (T2DM) patients; B: T2DM patients from normal controls; C: Discriminating DPN patients from T2DM patients; D: T2DM patients from normal controls. AUC: Area under the curve; T2DM: Type 2 diabetes mellitus; DPN: Diabetic peripheral neuropathy; TC: Training cohort; VC: Validation cohort.
