Data are presented as absolute number (percentage) or mean ± SD. P-values refer to the comparison between no factor and factor group. Categorial data were compared using the chi-square test. Continuous data were compared using the Mann-Whitney U-test. Bold face indicates p-values < 0.05. SD, standard deviation; RBC, Red blood cells; PLT, Platelet concentrates; FFP, Fresh frozen plasma; TU, Transfusion units.
