Fig 2. BLYS, CD40, CD86, and CD40L genotypes in relation to antibody titers against the merozoite proteins.
Antibody titers were expressed as log-transformed reactivity indices (RI). For the SNP in the gene CD40L, men and women harboring the C allele were grouped and compared with individuals who did not possess this allele given that CD40L is located on chromosome X. Multivariate logistic regression analysis found no significant differences in the antibody titers between the different genotypes.
