Incidence of chronic kidney disease progression according to baseline albuminuria or proteinuria
| Albuminuria/proteinuria category* | Follow-up BP readings evaluated (n) | Patients (n) | CKD progression, n (%)† |
| Normal to mildly increased (A1) | 26,802 | 2763 | 160 (5.8) |
| Moderately increased (A2) | 10,632 | 1135 | 124 (10.9) |
| Severely increased (A3) | 8700 | 1103 | 429 (38.9) |
| Total | 46,134 | 5001 | 713 (14.3) |
*Categories for albuminuria and proteinuria are based on the Kidney Disease Improving Global Outcomes guidelines.
†Composite of ≥50% reduction in GFR from baseline or ESRD requiring RRT (long-term dialysis or renal transplantation). Percentage is relative to specified albuminuria/proteinuria stratum.
BP, blood pressure; CKD, chronic kidney disease; ESRD, end-stage renal disease; GFR, glomerular filtration rate; RRT, renal replacement therapy.
