Fig 1 Preoperative hemoglobin levels in group 1 increased significantly from before first donation to 7 days before surgery. The mean hemoglobin level at 7 days before surgery was significantly higher in group 1. ap < 0.05 in comparison between both groups. bp < 0.05 versus 21 days before surgery.

Fig 2 The number of reticulocytes began to increase in group 1 significantly, although group 2 did not show a significant increase. The reticulocyte count at just before surgery was significantly higher in group 1. ap < 0.001 in comparison between both groups. bp < 0.01 versus 21 days before operation.

Fig 3 Estimated hemoglobin increase (EHI) in group 1 was significantly higher than in group 2 at 7 days before operation and just before operation. ap < 0.001 in comparison between both groups. The Annals of Thoracic Surgery 1999 68, 1652-1656DOI: (10.1016/S0003-4975(99)00755-9)
