From: Lower versus higher hemoglobin threshold for transfusion in ARDS patients with and without ECMO

Fig. 2

Hemoglobin concentrations and transfusion requirements between the lower-threshold group and higher-threshold group. The hemoglobin concentrations at ARDS onset (a), the number of transfused RBC units within 28 days of ARDS therapy (b), and the hemoglobin concentrations within 28 days of ARDS therapy (c) are presented. Gray boxes help to visualize the coherence of the range of individual hemoglobin thresholds that was used for grouping and the hemoglobin concentrations at admission and within 28 days of ARDS therapy. Median daily time-weighted average hemoglobin concentrations during 28 days of ARDS therapy in the lower-threshold group and higher-threshold group (d). Daily time-weighted average hemoglobin concentrations overcome the complexity that number and timing of daily blood gas samples were not exactly the same in all patients. First values were the baseline hemoglobin concentrations at onset of ARDS. Day 0 was defined as the time of ARDS onset to the end of that day. Data are shown as median and 25th and 75th percentiles
