Oxidative Stress in Diabetic Nephropathy with Early Chronic Kidney Disease

Table 1

(a) Categories of glomerular filtration rate in chronic kidney disease. GFR categories mentioned are based on the agreed-upon modifications reported in [6]. (b) Categories of albuminuria in chronic kidney disease. Shown are the categories that correspond to the excretion rate of urinary albumin. All are complications caused by diabetes mellitus. Modified and reported in [6].

(a)

Category of glomerular filtration rate (GFR)
Category	GFR (mL/min/1.73 m^2)	Term
G1	90	Normal or high
G2	60–89	Slightly decreased
G3a	45–59	Slight or moderately decreased
G3b	30–44	Moderately-to-severely decreased
G4	15–29	Severely decreased
G5	<15	Renal insufficiency

(b)

Category	AER (mg/24 h)	AER (mg/mmol)	AER (mg/g)	Term
A1	<30	<3	<30	Normal to slightly elevated
A2	30–300	3–30	30–300	Moderately elevated
A3	>300	>30	>300	Severely elevated

AER: albumin excretion rate.
