we collected data based on the
MDRD-GFR equation from the collaborators as the CKD-EPI
equation had not yet been reported when the collaboration was
first established. Indeed, ithasbeensuggestedthat the CKD-EPI
equation might be superior to the MDRD-GFR equation for
estimating GFR in people with eGFR of ≥60 mL/min/1.73 m

but both equations have similar accuracy in people with eGFR
