Revised Equations for Estimated GFR From Serum Creatinine in Japan

Estimation of glomerular filtration rate (GFR) is limited by differences in creatinine generation among ethnicities. Our previously reported GFR-estimating equations for Japanese had limitations because all participants had a GFR less than 90 mL/min/1.73 m2 and serum creatinine was assayed in different laboratories.Diagnostic test study using a prospective cross-sectional design. New equations were developed in 413 participants and validated in...
