Figure 4: Changes in red cell distribution width (RDW) in severe> sepsis patients. (RDW was measured as part of the complete blood> count at baseline (Before, ?) and every 24 hours for up to 96 hours> (After, ). Baseline RDW was abnormally high (>15%) in all three> groups. While RDW values did not change in the Lo and Hi groups,> there was a significant increase in RDW values in the placebo group> (p=0.03, paired t test). RDW is reported as a coefficient of variation> (percentage) of red blood cell volume.)
