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.
