The association of IL-10 expression based on IL-10 genotype. A, the association of IL-10 expression based on -1082 genotype. Genotypic groups were grouped according to a recessive model of inheritance. We found a significant association between -1082 genotype and IL-10 expression (P = .0006). B, The association of IL-10 expression based on -592 genotype. Genotypic groups were grouped according to a dominant model of dominance. There was no significant association between -592 genotype and IL-10 expression (P = .2180). Abbreviations: IL, interleukin; VL, viral load; k, thousands.
