In the TB group, decreasing levels of TNF (β coefficient: -0.12; 95%CI: -0.21 to 0.04, p=0.003), sCD14 (β coefficient: -0.18; 95%CI: -0.29 to -0.07, p=0.002) and sCD163 (β coefficient: -0.05 95%CI: -0.09 to -0.01, p=0.01) were associated with an increase of one Hb (log2) unit. The gene discussed is CD163; the disease is tuberculosis.
