Prevalence of CKD awareness by MDRD Study eGFR (n = 26,213) and CKD-EPI eGFR (n = 23,572) stages. Bars indicate 95% confidence intervals. CKD stages are defined as follows: Stage 1, eGFR ≥ 90 mL/min/1.73 m2 with ACR ≥ 30 mg/g; Stage 2, eGFR 60-89 mL/min/1.73 m2 with ≥ ACR 30 mg/g; Stage 3, eGFR 30-59 mL/min/1.73 m2; Stages 4-5, eGFR < 30 mL/min/1.73 m2. ACR, albumin-creatinine ratio; CKD, chronic kidney disease; CKD-EPI, Chronic Kidney Disease Epidemiology Collaboration; eGFR, estimated glomerular filtration rate; MDRD, Modification of Diet in Renal Disease.
