Prevalence of albuminuria (ACR 30–300 mg/g and ACR > 300 mg/g) estimated from NHANES and from KEEP without and with inverse probability weighting, 2003–2012.

| ACR 30–300 mg/g | 2,498 | 5.33 (5.03–5.65) | 11,663 | 10.29 (10.11–10.47) | 10.47 (10.00–10.95) | 7.14 (6.86–7.43) | 6.20 (5.61–6.85) |
| ACR > 300 mg/g | 472 | 0.86 (0.77–0.96) | 1,425 | 1.26 (1.19–1.32) | 1.33 (1.20–1.47) | 0.62 (0.55–0.70) | 0.54 (0.45–0.66) |
Weighted estimates accounted for NHANES sampling design or self-selection by KEEP. KEEP GEE estimates accounted for participant clustering within regional affiliates. ACR – urinary albumin-creatinine ratio; CKD – chronic kidney disease; KEEP – Kidney Early Evaluation Program; NHANES – National Health and Nutrition Examination Survey.
