Risk categories for renal survival on initial biopsy (n = 94)

Number of patients (% total)	Interstitial inflammation <5%, n (%)	Interstitial inflammation ≥5–25%, n (%)	Interstitial inflammation ≥25–50%, n (%)	Interstitial inflammation ≥50%, n (%)
IFTA <5%	38 (40)	13 (13)	2 (2)	3 (3)
IFTA ≥5–25%	8 (8)	11 (12)	3 (3)	6 (6)
IFTA ≥25–50%	1 (1)	1 (1)	3 (3)	2 (2)
IFTA ≥50%	1 (1)	1 (1)	0	1 (1)

Green, low risk (n = 59, 25% ESRD or RRT, 12% mortality); yellow, intermediate risk (n = 18, 44% ESRD or RRT, 17% mortality); red, high risk (n = 17, 59% ESRD or RRT, 18% mortality).
