Data are mean ± SD or mean ± SD (n) if n differs. BP = arterial blood pressure; CVP = central venous pressure. P values are for paired comparisons from before to after transfusion (within), and unpaired comparisons between transfusion groups; treatment groups are all erythrocytes as described in the text.
