Fig. 1. Mean values of ABO antibody titers or neutralizing capacities in ten blood group O EDTA samples converted to binary logarithms according to diluents in Panel II. Pooled fresh frozen plasmas (FFP) were utilized as diluents for the O EDTA samples, with each pooled FFP comprising blood bag segments from 15 FFP samples of the same ABO blood group. The symbols above bars in ‘ABO antibody titer’ repsent a significant difference compared to normal saline (NS). *P<0.001; ^†P<0.01; ^‡P<0.05. Refer to for information on neutralizing capacity.
Abbreviation: NS, 0.9% normal saline.
