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 m2. More studies are necessary to verify the accuracy of the JSN-CKDI coefficient and JSN-CKDI equation in other settings in Japan and elsewhere in Asia.
