TABLE 6.

C4d status in relation to DSA status in biopsies with DSA test results

	Number of biopsies C4d‐positive as fraction (%) of biopsies tested for both C4d and DSA
	DSA‐negative	DSA‐positive	Fisher's test p value of DSA status versus C4d status
All biopsies	48/632 (8%)	151/493 (31%)	7 × 10⁻²⁴
No rejection	29/444 (7%)	42/234 (18%)	9 × 10⁻⁶
All mABMR	16/116 (14%) ^a	98/224 (44%)	1 × 10⁻⁸
EABMR	7/64 (11%)	36/92 (40%)	0.0001
FABMR	6/32 (19%)	53/100 (53%)	0.0009
LABMR	3/20 (15%)	9/32 (28%)	0.33

^{^a}

DSA‐negative mABMR was more often C4d‐positive than DSA‐negative No rejection (p = .02).
