Fig 1 Homologous blood usage: number of patients requiring homologous blood transfusion. There was a significant reduction in the number of patients requiring homologous banked blood in the autotransfusion group. Pearson χ2p = 0.002.

Fig 2 Homologous blood usage: number of units of blood per patient. There was a significant reduction in the mean number of units per patient in the autotransfused group compared with controls. Mann–Whitney p = 0.029. The Annals of Thoracic Surgery 2004 77, 1553-1559DOI: (10.1016/j.athoracsur.2003.10.045)
