Figure 4. Interaction between rs13382811 and rs6469937 in the combined European population groups under a recessive model. Individuals are grouped by the presence of the homozygous risk genotypes and compared to risks with at least one protective allele for rs13382811 (risk allele = C, protective allele = T) or rs6469937 (risk allele = A, protective allele = G). The odds ratios (ORs) are given relative to those samples with at least one protective allele for both markers. It should be noted that these results are reversed from those in the Han Chinese population.
