Figure 5. The forest plots of meta-analysis compared the phenotypes of polypoidal choroidal vasculopathy between different genotypes of HTRA1rs11200638. 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 and C: Comparison between TT and GG; B and D: Comparison between TG and GG. A and B: Bilaterality; C and D: Greatest linear diameter on fundus fluorescence angiography.
