Fig. 2From: Immunogenetic markers associated with a naturally acquired humoral immune response against an N-terminal antigen of Plasmodium vivax merozoite surface protein 1 (PvMSP-1)Interaction between SNPs in the codominant model. The diagonal contains the p values of the likelihood ratio test (LRT) for the effect of each SNP individually. The upper triangle in the matrix contains the p values for the interaction log-LRT. The lower triangle contains the p values from LRT comparing the two-SNP additive likelihood to the best finding of the single-SNP model [35]Back to article page
