Lund-Malmö GFR estimating equation outperforms MDRD and CKD-EPI across GFR, health in older adults: the cardiovascular health study.

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.

Duplicate; RESULTS: A trend towards decreasing eGFRs between the study years was observed using both equations, but the trend was more substantial when using the MDRD equation. 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 … 2014-06-13 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).

Eligible studies compared the MDRD (Modification of Diet in Renal Disease) Study and CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) equations Because the MDRD Study equation was developed using a nonstandardized creatinine method, a Laboratory Working Group of the National Kidney Disease INDEX WORDS: MDRD Study equation; Cockcroft Gault equation; drug dose recommendation.

This equation markedly Diet in Renal Disease (MDRD) Study equation has been shown to be reliable in estimating GFR from serum creatinine, when the patient's age, sex, and race are.

Recently, a new estimator based on creatinine, the CKD-EPI equation, has been proposed which is presumed to better perform in normal GFR ranges.

Equations were not compared in a separate study sample. Conclusions: The 4-variable MDRD Study equation provides reasonably accurate GFR estimates in patients with chronic kidney disease and a measured GFR of less than 90 mL/min per 1.73 m2.

예로서, 건강한 잠재적 신장 공여자의후향적 연구에서 MDRD study equation은 9-29% 정도 measured GFR (iothalamate clearance)보다 낮게 평가하였습니다. Even in the CKD-EPI study, though there was better representation for blacks (around a third, up from the 197 participants in the MDRD study), Asians still constituted a very small proportion. To address these, there are many different studies out there which have applied correction factors to the CKD-EPI equation for their own population. A third formula, the CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) equation, is based on the same four variables as the MDRD Study formula but uses a 2-slope “spline” to model study yielded a Japanese ethnic coefﬁcient of 0.808 for the IDMS MDRD study equation.

Using the MDRD Study equation, the prevalence of CKD was estimated to be higher (13.4 % ) than when using the CKD-EPI equation (11.5 % ) . However, to our knowledge, there are no studies comparing these equations in assessing eGFR trends in representative population samples.

Noninvasively estimates the measured GFR to determine degree or presence of decreased kidney function. The MDRD equation performs equally to the newer CKD-EPI Equation in patients with GFR of < 60 ml/min/1.73m2. Performs superiorly to the Cockcroft-Gault Equation.

The Cockcroft‐Gault (CG) equation provides an estimate of creatinine clearance and is the equation most commonly used to determine drug dosages in patients with impaired kidney function. The Modification of Diet in Renal Disease (MDRD) study equation has also been proposed for this purpose.
