Figure 6. Meta-analysis of the association of single nucleotide polymorphism (SNP) rs3825942 with a combined group of 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. Subgroup meta-analysis indicated that the ORs SNP rs3825942 G allele is consistent in Caucasian and Japanese.
