In the non-TB group, decreasing levels of IL-6 (β coefficient: -0.09; 95%CI: -0.12 to -0.05; p<0.001), LTB4 (β coefficient: -0.03; 95%CI: -0.06 to -0.01; p=0.003) and sCD14 (β coefficient: -0.08; 95%CI: -0.14 to -0.01; p=0.031) as well as increasing levels of IL-10 (β coefficient: 0.03; 95%CI: 0.01 to 0.06; p=0.034) and IL-1β (β coefficient: 0.04; 95%CI: 0.01 to 0.06; p=0.009) were independently associated with an increase of one Hb (log2) unit. Here, GSTM1 is linked to tuberculosis.
