Additional file 3 of Plasma fractalkine is a sustained marker of disease severity and outcome in sepsis patients

Elevated fractalkine plasma levels are associated with short- and long-term mortality. Patient blood was drawn within 24 hours of admission to the ICU (day 0) and at days 2 and 4. Fractalkine levels are shown for survivors and non-survivors at day 7 (a), day 90 (b) and one year (c) after ICU admission. Box and whisker diagrams depict median and lower quartile, upper quartile, and their respective 1.5 IQR as whiskers (as specified by Tukey). Dotted lines in boxes, median level in healthy volunteers. ***P
