Ferritin and inflammation markers. Plasma levels of ferritin (a), C-reactive protein, (b), and α-1-acid-glycoprotein (c) on days 0, 7, 14, 28, and 42 post-admission. Geometric means (filled circle) and standard deviations (bars) are shown. Number of samples (N) and statistically significant differences (*P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001) relative to day 42 are indicated along the top of each panel. Normal reference area is indicated by grey shading
