Background: Current equations for estimated glomerular filtration rate (eGFR) that use serum creatinine or cystatin C incorporate age, sex, and race to estimate measured GFR. However, race in eGFR equations is a social and not a biologic construct.
Methods: We developed new eGFR equations without race using data from two development data sets: 10 studies (8254 participants, 31. Read More
