eGFR was calculated by a four‐variable MDRD equation (eGFRMDRD), CKD‐EPI creatinine equations (eGFRCr), CKD‐EPI cystatin C equation (eGFRCys) and CKD‐EPI creatinine‐cystatin equation (eGFRCrCys). Participants were divided into eGFR categories (<30, 30‐59, 60‐89, ≥90mL/min/1.73m2)...
Methods GFR was estimated in 208 patients with cardiovascular diseases by Tc-DTPA dynamic renal imaging, and the eGFR was derived from 8 equations using different variables. Results In patients with chronic kidney disease (CKD) stages 1-3, the eGFR calculated suing serum creatinine (SCr)-based ...
