Forest plot of risk estimates for the association between systemic hypertension and open-angle glaucoma in all included studies. CI, confidence interval.
Figure 3.
Funnel plots of the odds ratio of developing open-angle glaucoma for identifying publication bias.
Odds ratios are displayed on a logarithmic scale. A, all included populations; B, Asian populations; C, Western populations.

Meta-regression analysis between the pooled odds ratio and age for open-angle glaucoma in all included studies.
Odds ratios are displayed on a logarithmic scale (P = 0.28).
