ACC indicates aortic cross‐clamping; CI, confidence interval; CPB, cardiopulmonary bypass; ICU, intensive care unit; OR, odds ratio; RBCs, red blood cells; WMD, weighted mean difference.
*Indicates statistically significant.
†Data as percentage are odds ratios, mean values are weighted mean differences.
