Figure 1. Meta-analysis of the distribution of single nucleotide polymorphism (SNP) rs1048661 between exfoliation syndrome (XFS) and exfoliation glaucoma (XFG). 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 difference of distribution of the SNP rs1048661 G and T allele between XFS and XFG.
