Correlation between hemolysis variables in parent versus transfer bags at 39 to 42 days using samples from recalled donors. Scatter plots shown for percent spontaneous storage hemolysis (A), percent osmotic hemolysis (B), percent oxidative hemolysis (C), and percent mechanical hemolysis (D). Percent hemolysis of blood samples derived from parent unit is shown on the x-axis and that from transfer bag on y-axis. Pearson correlation statistics, p values, and sample sizes are shown on each panel.
