In order to distinguish DKD patients in the normal albuminuria group, microalbuminuria group, and macroalbuminuria group, the areas under the receiver operating characteristic curve (AUC-ROCs) of VEGF-C was 0.668 (95%CI: 0.531–0.805), 0.790 (95%CI: 0.678–0.901), and 0.850 (95%CI: 0.756–0.944), respectively. The gene discussed is VEGFC; the disease is diabetic kidney disease.
