KIM-1 score, renal functional indices, and tacrolimus levels in three groups of renal transplant biopsies.

	Three groups	KIM-1 scores	Serum Cr (mg/dL)	Serum tacrolimus (ng/dL)
Group 1	Controls (KIM-1 negative) N = 13	0.00 ± 0.00	1.24 ± 0.09	8.53 ± 0.76
Group 2	KIM-1 + in all cortical PT N = 28	1.86 ± 0.16∗	4.20 ± 0.49∗	5.92 ± 0.61∗
Group 3	KIM-1 + in PT of medullary rays N = 43	1.16 ± 0.10∗#	1.89 ± 0.26#	10.85 ± 0.60∗#

^∗ p < 0.05 versus group 1, ^# p < 0.05 versus group 2; PT: proximal tubules.
