Adjusted	1.14 (0.85–1.54)	0.377	1.66 (1.28–2.15)	<0.001	1.45 (1.02–2.07)	0.039
Postoperative stroke
Crude	1.22 (0.67–2.21)	0.515	1.02 (0.59–1.75)	0.956	0.83 (0.40–1.73)	0.625

ACP = antegrade cerebral perfusion, HCA = hypothermic circulatory arrest, RCP = retrograde cerebral perfusion, OR = odds-ratio, and CI = confidence interval.
