Article in Health science reports, 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
Background and Aims: In Ethiopia, glaucoma and related cases account for 5.2% of the irreversible blindness and is the fifth main cause of blindness. The aim of this study was to investigate the time to blindness and associated factors among glaucoma patients under treatment at government hospitals in Amhara region, Ethiopia. Methods: A retrospective cohort study using a gamma shared frailty accelerated failure time model was conducted at 5 randomly selected public hospitals in Amhara region. About 1102 glaucoma patients, whose follow ups, from January 2018 to December 2023 were randomly selected using stratified random sampling technique. Results: The results of the multivariable Gamma Shared Frailty accelerate failure time model indicates that age [ϕ = 0.694; 95% CI: (0.408, 0.773)], literate glaucoma patients [ϕ = 1.163, 95% CI: (1.062, 1.206)], urban glaucoma patients [ϕ = 1.157; 95% CI: (1.049, 1.274)], non-hypertensive glaucoma [ϕ = 0.812; 95%: (0.673, 0.979)], non-diabetic glaucoma patients [ϕ = 0.949; 95% CI: (0.533, 0.687)], housewives [AOR = 0.772; 95% CI: (0.428, 0.975)], farmers Glaucoma patients (ϕ = 0.969; 95% CI: (0.735, 0.999)], moderate glaucoma stage [ϕ = 0.791; 95% CI: (0.419, 0.890)], advanced stage glaucoma patients [ϕ = 0.959; 95% CI: (0.703, 0.998)], glaucoma patients with cup-disk ratio (CDR) > 0.7 [ϕ = 0.931; 95% CI: (0.739, 0. 998)] and glaucoma patients with normal IOP (ϕ = 1.058; 95% CI: (1.019, 1.285)] significantly affected the time to blindness for glaucoma patients. Conclusion: Age, lack of education, and residing in a rural area were all associated with a shorter time to blindness. Conversely, patients with better IOP control, no concurrent hypertension or diabetes, and those with a lower cup-to-disc ratio (CDR) showed a longer time to blindness. The significant frailty effect confirmed that there is substantial variation in patient outcomes across different hospitals, likely due to differences in healthcare quality and provision. To minimize this disparity and ensure consistent, high-quality care, it is critically important to standardize treatment protocols across all facilities.
