Distribution of total fibrosis, focal IF/TA, and diffuse renal fibrosis in experimental kidney diseases with different types of injury.

Model	% Total Fibrosis	% Focal IF/TA	% Diffuse Fibrosis
NTN (n = 5)	10 (8.5–15)	10 (8.5–13.5)	0 (0–1.5)
UUO (n = 5)	15 (8.5–20)	0 (0–2)	15 (11.5–20)
FAN (n = 5)	25 (20–25)	15 (15–20)	5 (5–7.5)
p value	0.0123	<0.0001	<0.0001

Median values and IQR are shown. The Kruskal–Wallis test was used for between-group comparison. Abbreviations: FAN—folic acid-induced nephropathy; NTN—nephrotoxic serum-nephritis; UUO—unilateral ureteral obstruction.
