Figure 4. The forest plots of meta-analysis compared the phenotypes of polypoidal choroidal vasculopathy between different genotypes of LOC387715rs10490924. Blue squares indicate the study-specific odds ratio (OR). Green squares indicate the study-specific mean difference (MD). The size of the box is proportional to the weight of the study. Horizontal lines indicate 95% confidence interval (CI). A diamond indicates the summary OR (blue) or MD (green) with its corresponding 95% CI. A, C, E, G, I, K, M and Q: comparison between TT and GG; B, D, F, H, J, L, N and R: comparison between TG and GG. O: comparison between TT and TG + GG; P: comparison between T and G allele. A and B: Gender distribution; C and D: Age of onset; E and F: Bilaterality; G and H: Best-corrected visual acuity; I and J: Greatest linear diameter on fundus fluorescence angiography; K and L: Greatest linear diameter on indocyanine green angiography; M-P: Vitreous hemorrhage; Q and R: Best-corrected visual acuity at 12 months after photodynamic therapy or combined therapy.
