IL10 and brucellosis: Generally, significant relevance of IL-10 polymorphisms with Brucellosis sensibility was only found in Asian population of position -819 (T vs. C: OR 0.60, 95% CI 0.44–0.82, P = 0.001) (Fig. 2b), homozygote comparison genetic model (TT vs. CC: OR 0.24, 95% CI 0.09–0.62, P = 0.003) (Fig. 2d) and recessive genetic model (TT vs. TC/CC: OR 0.22, 95% CI 0.05–0.91, P = 0.036) (Fig. 2a).
