Table 2 Mean estimates of iron parameters derived from the linear mixed model

From: Iron metabolism in critically ill patients developing anemia of inflammation: a case control study

Iron parameter AI Septic controls, high Hb Non-septic controls, high Hb
Iron (µmol/L) 3.8 (3.2–4.5)* 5.6 (4.8–6.6) 6.3 (5.4–7.3)
Transferrin (g/L) 1.3 (1.2–1.5)* 1.6 (1.5–1.8) 1.9 (1.7–2)
Transferrin saturation (%) 10 (8–12)* 14 (11–16) 13 (11–15)
Ferritin (µg/L) 1134 (548–2346) 473 (229–976) 314 (152–648)
Haptoglobin (g/L) 3.5 (3.2–3.9)* 2.7 (2.4–3) 2.5 (2.2–2.8)
Hepcidin (pg/ml) 20.7 (15.1–28.5) 12.9 (9.4–17.9) 7.3 (5.4–9.8)
Erythroferrone (pg/ml) 15.5 (9.3–26) 9.6 (5.8–16) 18.7 (11.2–31)
sTfR (µg/ml) 0.83 (0.68–1.01) 0.7 (0.55–0.87) 0.70 (0.57–0.86)
IL-6 (pg/ml) 14.4 (5.1–40.9) 8.0 (1.5–43.0) 2.0 (0.4–10.9)
  1. Data are expressed as (back-transformed) mean estimates of iron parameters for all patients per group at all time points, with 95% confidence interval
  2. Differences between mean estimates are tested by contrasts. * p < 0.05 AI compared to septic controls,  p < 0.05 AI compared to non-septic controls
