Fig. 1. Mean values of ABO antibody titers or neutralizing capacities in group O fresh frozen plasma (FFP) converted to binary logarithms according to the diluents in Panel I. EDTA plasmas with Lewis b antigen positivity were used as diluents for the group O FFP. The black lines and asterisk (*) above the bars in ‘ABO antibody titer’ represent the mean value of 0.9% of normal saline of control group and a significant difference vs. the control group, respectively. *P<0.001; ^†P<0.05. Neutralizing capacity was the titer differences assessed by subtracting the binary logarithm value of the titer in each blood group from that in 0.9% normal saline.
