Prevalence of stage 3 chronic kidney disease (CKD) is increasing according to the NHANES study. Prevalence has been calculated using the MDRD study equation for estimating glomerular filtration rate (GFR). Recently, a new estimator based on creatinine, the CKD-EPI equation, has been proposed which is presumed to better perform in normal GFR ranges.

In the entire population, the CG equation underestimated measured GFR (P < 0.001), whereas the biases of the MDRD Study and CKD-EPI equations were not significantly different from zero (P = 0.6 and P = 0.2, respectively). The CG equation had the poorest overall accuracy, with the lowest P 10 and a lower P 20 than that of the CKD-EPI equation . 2017-12-20 MDRD equation The 4-variable MDRD Study equation was developed in 1999 using data from 1,628 patients with CKD with GFR from approximately 5 to 90 milliliters per minute per 1.73 m 2 .

Appropriate for use with ing the results of different MDRD formulas with the true GFR as measured by a reference method are rare (10,11). The aim of the present study was to evaluate the diagnos-tic precision of the C&G formula, the MDRD6, the MDRD7 equations, as well as the aMDRD formula in an unselected consecutive cohort of renal transplant recipients that had The Cockcroft-Gault (CG) equation requires a body weight parameter, whereas the Chronic Kidney Disease-Epidemiology Collaboration (CKD-EPI) and Modification of Diet in Renal Disease (MDRD) Study equations do not.

The latest versions of these equations are based on broad collaboration, are expressed for Modification of the Modification of Diet in Renal Disease (MDRD) Study equation for Japan. GFR estimates using the IDMS MDRD Study equation with the JSN-CKDI coefficient or the new JSN-CKDI equation are more accurate than the IDMS MDRD Study equation in hospitalized Japanese patients with eGFR less than 60 mL/min/1.73 m(2).
