Table 5 Severity score system
Clinical characteristics | Points |
|---|---|
Past disease activity score | Â |
  Has the subject ever received dialysis? | No = 0, Yes = 1 |
  Has the subject ever received a kidney transplant? | No = 0, Yes = 1 |
  Did the subject receive dialysis or transplant at age ≤ 5 years? | No = 0, Yes = 1 |
Current estimated glomerular filtration rate (eGFR, ml/min/1.73m2) score | Â |
  eGFR > 60 | 0 |
  30 < eGFR ≤ 60 | 1 |
  15 < eGFR ≤ 30 | 2 |
  eGFR ≤ 15 | 3 |
Severity Score (past disease activity score + current eGFR score) | 0 to 6 |
