Notably, multiple logistic regression analyses uncovered a negative association between parasitemia and the IL6 rs1800795 CG genotype (OR = 0.45, P = 0.015, 95% CI 0.24 −0.86) and a positive association between parasitemia and HIV infection (OR = 2.18, P = 0.039, 95% CI 1.04–4.58) (Table 5). This evidence concerns the gene IL6 and parasitic infectious disease.
