OBJECTIVE The Cockcroft-Gault (CG) and Modification of Diet in Renal Disease (MDRD) equations previously have been recommended to estimate glomerular filtration rate (GFR). We compared both estimates with true GFR, measured by the isotopic (51)Cr-EDTA method, in newly diagnosed, treatment-naïve subjects with type 2 diabetes. RESEARCH DESIGN AND METHODS A total of 292 mainly normoalbuminuric (...
