ADIPOQ and tuberculosis: Additionally, applying Pearson's rank correlation, we also found statistically significant correlations between TB and adiponectin (r = 0.238; P = 0.001), transferrin (r = −0.213; P = 0.003), iron (r = 0.201; P = 0.005), transferrin saturation (r = 0.307; P < 0.001), ferritin (r = 0.173; P = 0.017), Apo A (r = −0.249; P < 0.001), lymphocytes (r = −0.223; P = 0.002), and IL-6 (r = −0.193; P = 0.008).
