N0 (0 points) >25%	57 (59.4%)
N1 (4 points) 10%-25%	13 (13.5%)
N2 (6 points) <10%	26 (27.1%)
Tubular atrophy/interstitial fibrosis (T)
T0 (0 points) ≦25%	41 (42.7%)
T1 (2 points) >25%	55 (57.3%)
Renal function at the time of diagnosis (eGFR; G)
G0 (0 point) >15 mL/min/1.73m2	76 (79.2%)
G1 (3 points) ≦15 mL/min/1.73m2	20 (20.8%)

ANCA, anti-neutrophil cytoplasmic antibody; eGFR, estimated glomerular filtration rate
