Number of patients (% total)	Interstitial inflammation <5%, n (%)	Interstitial inflammation ≥5–25%, n (%)	Interstitial inflammation ≥25–50%, n (%)	Interstitial inflammation ≥50%, n (%)
IFTA <5%	21 (22)	7 (7)	0	0
IFTA ≥5–25%	5 (5)	13 (14)	4 (4)	3 (3)
IFTA ≥25–50%	1 (1)	6 (6)	8 (9)	4 (4)

Green, low risk (n = 33, 15% ESRD or RRT, 3% mortality); yellow, intermediate risk (n = 24, 38% ESRD or RRT, 9% mortality); red, high risk (n = 37, 57% ESRD or RRT, 24% mortality).
