Incidence Rates (per 1,000 person-years) of Outcomes according to eGFR by the CKD-EPI and MDRD study equations. Incidence rates of (A) ESRD, (B) all-cause mortality, (C) CHD, and (D) stroke and eGFR (ml/min/1.73m2) by the CKD-EPI equation (blue and thick) and the MDRD equation (red) without (solid lines) and with (dash lines) adjustment for mean values of age, gender, and race. The long-dash two dots lines in the panel A demonstrate kernel density plots of the distributions of eGFRCKD-EPI (light blue and thick) and eGFRMDRD (magenta).
