Figure 2. Definition and Prognosis of Chronic Kidney Disease by GFR and Albuminuria Categories, KDIGO 2012.
GFR indicates glomerular filtration rate; KDIGO, Kidney Disease Improving Global Outcomes. Categories are grouped by risk of progression, which includes chronic kidney disease progression, defined by a decline in GFR category (accompanied by a ≥25% decrease in estimated GFR from baseline) or sustained decline in estimated GFR greater than 5 mL/min/1.73 m2 per year. Green indicates low risk (if no other markers of kidney disease and no CKD); yellow, moderately increased risk; orange: high risk; and red, very high risk.
