[Diagnostic ability of Chronic Kidney Disease Epidemiology Collaboration and Modification of Diet in Renal Disease-4 equations to estimate glomerular filtration rate in with multimorbidity patients].

Background And Objective: The Modification of Diet in Renal Disease (MDRD) equation is recommended by most scientific societies to calculate the estimated glomerular filtration rate (GFR). Recently the group Chronic Kidney Disease Epidemiology Collaboration (CKP-EPI) has published a new, more precise and accurate equation. We have analyzed its behavior in a group of polypathological patients (PP) and compared it with the classic MDRD-4.
