Figure S1. Correlation of serum and urine ferritin levels with inflammatory cytokine levels. Serum and urine ferritin levels determined by using a protein array were correlated with cytokine levels measured in the same assay. Urine ferritin levels correlated with IL-6 (R = 0.94, P < 0.001), TNF α (R = 0.71, P = 0.022), and IL-1α (P = 0.073). Serum ferritin levels showed weaker correlations with proinflammatory cytokine levels.
