Risk of retinal artery occlusion in patients with primary open-angle glaucoma: a retrospective cohort study.
Article in International journal of retina and vitreous, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTo evaluate the risk of Retinal Artery Occlusion (RAO) in individuals with Primary-Open Angle Glaucoma (POAG) using a large-scale real-world database.
methodsThis retrospective cohort study used the TriNetX Global Collaborative Network to analyze electronic health records from 145 healthcare organizations. Adults aged 18 years or older with POAG were compared with non-POAG controls. Propensity score matching (PSM) was performed 1:1 on 10 baseline characteristics. The primary outcome was incident RAO occurring from one day after the index POAG diagnosis up to 5 years of follow-up. Hazard ratios (HRs) were calculated using Cox proportional hazard models. Kaplan-Meier analysis was conducted to compare RAO-free survival using log-rank tests.
resultsAfter PSM, there were 260,677 patients in each cohort (50.9% female; mean age 68.2 years). POAG patients had a significantly increased risk of RAO compared with controls (3.46 vs. 1.94 per 10,000; HR 2.16; 95% CI, 1.94–2.42; p < .001). The association persisted in sex-stratified and extended follow-up analyses. Anti-glaucoma medications did not significantly alter risk.
conclusionsThis large-scale cohort study identifies POAG as an independently associated risk marker for RAO. These findings highlight the importance of vascular risk assessment in POAG management and highlight the need for increased vigilance for retinal ischemic events in this population.
