Meta-analysis of the
distribution of single nucleotide polymorphism (SNP) rs3825942
between exfoliation syndrome (XFS) and exfoliation glaucoma (XFG).
Squares indicate study-specific risk difference (RD); the size of the
box is proportional to the weight of the study; horizontal lines
indicate 95% confidence interval (CI); diamond indicates summary RD
with its corresponding 95% CI. Meta-analysis indicated there is no
statistical difference of distribution of the SNP rs3825942
G and A allele between XFS and XFG.
