Figure 1. Interaction between the rs13382811 and rs6469937 alleles in terms of myopia risk in the combined Han Chinese groups. The odds ratios (ORs) of combinations of genotypes at rs13382811 and rs6469937 are given relative to the homozygous protective genotypes, namely CC for rs13382811 and AA for rs6469937. NA: the odds ratio was not available because of the small number of samples with TT for rs13382811 and AA for rs6469937 (none in the case group and only one sample in the control group).
