* The known risk factors and variables with a p-value < 0.01 from univariate analysis (Supplementary Table S2) were included in this multivariate logistic regression analysis. OR: odds ratio; CI: confidence interval; MI: myocardial infarction; pRBC: packed erythrocytes; rScO₂: regional cerebral oxygen saturation.
