Table 3. Surgical re-exploration and resource usage after CABG according to total RBC units.

	Total RBC units transfused during CABG
	None		>0-2 U		>2 U
	Prasugrel	Clopidogrel	Prasugrel	Clopidogrel	Prasugrel	Clopidogrel
Surgical re-exploration for bleeding	0 (0) (n = 64)	1 (1.6) (n = 62)	0 (0) (n = 51)	0 (0) (n = 56)	11 (21.2) (n = 52)	3 (6.7) (n = 45)
Bleeding source identified by surgical re-exploration*	NA (n = 0)	1 (100) (n = 1)	NA (n = 0)	NA (n = 0)	8 (72.7%) (n = 11)	2 (66.7) (n = 3)
Hospital stay (d)	12 ± 9 (n = 63)	13 ± 15 (n = 62)	11 ± 5 (n = 51)	10 ± 4 (n = 56)	13 ± 11 (n = 52)	14 ± 9 (n = 45)
Postoperative ICU stay (h)	64 ± 109 (n = 59)	60 ± 102 (n = 59)	51 ± 42 (n = 49)	48 ± 34 (n = 54)	101 ± 192 (n = 52)	98 ± 113 (n = 44)

Data presented as n (%), with n in parentheses, number of subjects with nonmissing values for each category, or mean ± standard deviation. CABG, Coronary artery bypass grafting; ICU, intensive care unit; NA, not allowed because denominator was 0 (ie, no patients in category underwent surgical re-exploration); RBC, red blood cell.

^*Denominator consisted of patients who underwent surgical re-exploration.
