New Creatinine- and Cystatin C–Based Equations to Estimate GFR without Race

Abstract

New eGFR equations that incorporate creatinine and cystatin C but omit race are more accurate and led to smaller differences between Black participants and non-Black participants than new equations without race with either creatinine or cystatin C alone.
