Cuando un paciente se presenta con DRA sin una CrS basal, la utilizacion de una CrS estimada o calculada para imputar una TFG de 75ml/min acorde a una ecuacion MDRD
reversa es controversial, siendo relevante unicamente con los casos de DRA adquirido en la comunidad, ya que la ERC es comun en la poblacion en general.
Two equations are primarily used to estimate GFR: the MDRD
and CKD Epidemiology Collaborative (CKD-EPI) equations.
In addition, some studies indicate that cysC is a more sensitive predictor of CV morbidity than the measured GFR, as well as the calculated GFR using the MDRD
A newer equation, the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula, has also been proven to be equally effective as the MDRD
equation and may actually be better at measuring GFRs > 60 ml/min/1.73 [m.sup.2].
GFR was furthermore calculated using six estimating formulae, Cockcroft-Gault formula , the modification of diet in renal disease (MDRD
) equations using 4 and 6 variables [26, 27], and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations using creatinine alone (CKD-EPI Cr) , CysC alone (CKD-EPI CysC), or both CKD-EPI (Cr-CysC)  (Table 1).
Both HIVMA and New York State lean toward the Chronic Kidney Disease Epidemiology Consortium (CKD-EPI) equation, which may be more accurate than MDRD
for people with HIV.

Hereafter, there was partial renal function recovery (eGFR (MDRD
) of 10 mL/min/1.73 [m.sup.2]), after which mastectomy was performed without cessation of anticoagulant therapy.

We compare the reported eGFR values to expected values calculated using the 4-parameter MDRD
equation, defining an acceptable participant result to be within [+ or -]1 mL/min per 1.73 [m.sup.2] of the expected value.
