Interaction between rs13382811
in a Han Chinese population under a recessive model. Individuals are grouped by the presence of the homozygous risk genotypes
and compared with risks with at least one protective allele for rs13382811
(risk allele = T, protective allele = C) or rs6469937
(risk allele = G, protective allele = A). The odds ratios (ORs) are given relative to those samples with at least one protective
allele for both markers.
