From: Iron metabolism in critically ill patients developing anemia of inflammation: a case control study
Iron parameters and IL-6 levels per group over time. Time course of observed plasma iron parameters of the three groups; anemia of inflammation (AI), Septic, high Hb controls, non-septic, high Hb controls. Dotted line represents reference values. Statistically significant differences within the groups over time are indicated with: £ p < 0.05 AI group ‘Day 1 AI’ compared to ‘Admission’, # p < 0.05 non-septic, high Hb group ‘Day 1 AI’ compared to ‘Admission’, $ p < 0.05 non-septic, high Hb group ‘Day 3 AI’ compared to ‘Admission’, * p < 0.05 Septic, high Hb group ‘Day 3 AI’ compared to ‘Admission’, ¤ p < 0.05 AI group ‘Day 3 AI’ compared to ‘Admission’. Data are expressed as median with 25–75 interquartile ranges
