Results of univariate analysis comparing the rates of panel-reactive antibody positivity and donor-specific HLA antibody positivity between graft failure cases and engrafted controls

	Class I positive, no. (%)	Class II positive, no. (%)	Class I and/or II positive, no. (%)	P
Panel-reactive antibody results				> .221
Cases (n = 37)	16 (43)	10 (27)	16 (43)
Controls (n = 78)	21 (27)	13 (17)	25 (32)
Donor-specific HLA antibodies				< .001
Cases (n = 37)
	A: 1 (3)	DP: 6 (16)	9 (24)
	B: 4 (11)	DR: 0 (0)
	C: 0 (0)	DQ: 0 (0)
Controls (n = 78)
	A: 1 (1)	DP: 1 (1)	1 (1)
