  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
