MDRD4: Four-parameter MDRD study equation Description GFR is estimated with the 4-parameter Modification of Diet in Renal Disease (MDRD) study equation. Usage MDRD4(creatinine, sex, age, ethnicity, method = "IDMS")

GFR is estimated by the MDRD study equation and by the "new" CKD-EPI equations. The population screened consisted in 1992 people (47% of men). Mean serum creatinine was 0.86 +/- 0.20 mg/dL.

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 . It estimates GFR adjusted for body surface area and is more accurate than measured creatinine clearance from 24-hour urine collections or estimated by the Cockcroft and Gault formula. The MDRD Study equation was derived using samples from the 1st baseline visit (B0) during 1989–1991. The 253 samples used in the current study were from the 3rd baseline visit (B3, 3 months later) and selected sequentially from the serum repository. creatinine assays at the cleveland clinic 4 variable MDRD Study Equation, CKD-EPI Creatinine Equation (2009), CKD-EPI Cystatin C Equation (2012) and CKD-EPI Creatinine-Cystatin C Equation (2012) (with SI Units) using standardized serum creatinine, age, race, gender and serum cystatin C. programmed by Stephen Z.

Decrease of eGFR was associated with an increase in CKD and CVD risk factors. The MDRD equation yielded lower estimates of eGFR than the CKD-EPI equation, with small mean difference between the equations at low eGFR level but substantial at the level of only mildly decreased or near-normal to normal kidney function. Decrease of eGFR was associated with an increase in CKD and CVD risk factors. Three commonly used equations are the CKD-EPI creatinine equations, the Modification of Diet in Renal Disease (MDRD) Study equation, and Cockcroft and Gault equation. The 4-variable equation from the Modification of Diet in Renal Disease (MDRD) Study has been reexpressed for use with a standardized assay. Objective: To describe the performance of the revised 4-variable MDRD Study equation and compare it with the performance of the 6-variable MDRD Study and Cockcroft–Gault equations.

The severity of chronic kidney disease (CKD) is described by six stages; the most severe three are defined by the MDRD-eGFR value, and first three also depend on whether there is other evidence of kidney disease (e.g., proteinuria): 0) Normal kidney function – GFR above 90 (mL/min)/(1.73 m 2) and no proteinuria Nyman, Ulf et al.
