From: Asian Americans & chronic kidney disease in a nationally representative cohort

   Race
Outcome Statistic Asians White
ACR mg/g (A1, A2, A3) Mean ± SE 38.4 ± 7.1 25.7 ± 2.6
[CKD Stage 1–5] Median (Q1, Q3) 7.2 (4.8, 12.8) 6.8 (4.6, 12.1)
ACR ≥ 30 mg/g (A2) Mean ± SE 311.4 ± 68.1 201.4 ± 27.0
[CKD Stage 3] Median (Q1, Q3) 76.6 (39.8, 198.1) 57.4 (39.6, 120.8)
ACR > 300 mg/g (A3) Mean ± SE 1255.7 ± 298 1225.1 ± 204
[CKD Stages 4–5] Median (Q1, Q3) 628.2 (427.0, 1081.6) 657.1 (404.9, 1140.9)
eGFR ml/min/1.73 m2 (G1 to G5) Mean ± SE 101.2 ± 0.5 90.3 ± 0.3
[CKD Stages 1–5] Median (Q1,Q3) 103.3 (90.2, 115.5) 91.8 (76.8, 105.5)
eGFR < 60 ml/min/1.73 m2 (G3a-G5) Mean ± SE 48.6 ± 1.63 47.7 ± 0.57
[CKD Stage 3 to 5] Median (Q1, Q3) 51.8 (43.9, 57.5) 50.7 (41.9, 55.7)
eGFR < 45 ml/min/1.73 m2 (G3b-G5) Mean ± SE 34.1 ± 2.8 33.5 ± 0.9
[CKD Stage 3 to 5] Median (Q1, Q3) 37.1 (27.9, 42.6) 35.7 (30.6, 41.0)
  1. SE standard error; Q1 1st quartile, Q3 3rd quartile
  2. Note: UACR has a skewed distribution and therefore we would suggest using median (Q1, Q3), while eGFR is normally distributed and therefore would suggest using mean and standard error
  3. ACR ≥ 30 mg/g (A2) – Moderately increased; ACR > 300 mg/g (A3) – Severely increased; eGFR < 60 ml/min/1.73 m2 (G3a) – Mildly to moderately decreased; eGFR < 45 ml/min/1.73 m2 (G3b) – Moderately to severely decreased
