We also observed the positive correlations between TB Ag-NL with serum ferritin levels (r = 0.3284, p = 0.0295, n = 44) (Fig. 1E), IgG (r = 0.4290, p = 0.0029, n = 46) (Fig. 1H), and IgM (r = 0.5500, P < 0.0001, n = 46) (Fig. 1I); and negative correlations with Hemoglobin (HB) (r = -0.3267, p = 0.0285, n = 45) (Fig. 1F) and White blood cell (WBC) (r = -0.3032, p = 0.0429, n = 45) (Fig. 1G). The gene discussed is CD40LG; the disease is tuberculosis.
