Simple Cystatin C Formula for Estimation of Glomerular Filtration Rate in Overweight Patients with Diabetes Mellitus Type 2 and Chronic Kidney Disease

Figure 1

ROC curve analysis of diagnostic accuracy of calculated clearance from the C&G formula, the MDRD formula, the CKD-EPI formula, the CKD-EPI creatinine and cystatin formula, and the simple cystatin C formula. The GFR determined with ⁵¹CrEDTA was used as the gold standard and cut-off value was set at 60 mL/min/1.73 m².
