Comparison of Associations of Outcomes After Stroke With Estimated GFR Using Chinese Modifications of the MDRD Study and CKD-EPI Creatinine Equations: Results From the China National Stroke Registry

Background The CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) creatinine equation estimates glomerular filtration rate (GFR) more precisely than the MDRD (Modification of Diet in Renal Disease) Study equation. The risk implications of this equation have been compared with the MDRD Study equation in different demographic and clinical characteristics. However, whether a Chinese modification of this equation performs better than a...
