Figure 2.

Transfusion characteristics of the short-term and long-term storage groups. The hemoglobin concentrations at ARDS onset (A), the transfusion threshold (pre-transfusion hemoglobin) (B), the time from ARDS onset to transfusion of the first PRBC unit (C), the number of transfused PRBC units within 14 days of ARDS therapy (D), and the distribution of the storage age in both groups (E) are presented. The mean storage (SD) in each group and the mean difference between the groups is indicated.
