Figure 11. Meta-analysis of the association of single nucleotide polymorphism (SNP) rs1048661 with primary open angle glaucoma (POAG). Squares indicate study-specific odds ratio (OR); the size of the box is proportional to the weight of the study; horizontal lines indicate 95% confidence interval (CI); diamond indicates summary OR with its corresponding 95% CI. Meta-analysis indicated there is no statistical significant association of SNP rs1048661 with POAG.
