Comparison of Optic Nerve Head Parameters in Alcoholic Liver Disease Patients With Age-Matched Controls.
Article in Cureus, 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
Alcoholic liver disease (ALD) is associated with systemic neurodegeneration mediated by oxidative stress, mitochondrial dysfunction, and chronic inflammation. As the retina and optic nerve head represent extensions of the central nervous system, they may provide a non-invasive window for detecting alcohol-related neuroretinal damage. This retrospective case-control study compared optic nerve head and peripapillary retinal nerve fiber layer (pRNFL) parameters between 100 patients with ALD and 100 age- and sex-matched healthy controls who underwent comprehensive ophthalmic evaluation and spectral-domain optical coherence tomography imaging. Average and quadrant-wise pRNFL thicknesses were analyzed across predefined age groups using independent samples t-tests. Patients with ALD demonstrated a significantly reduced average pRNFL thickness compared with controls (p < 0.05), with more pronounced thinning observed in younger adults aged 21-40 years. Quadrant-wise analysis revealed predominant involvement of the nasal and temporal quadrants, with relative sparing of the inferior quadrant. An age-related decline in pRNFL thickness was observed in both groups; however, the rate of decline was greater among patients with ALD. These findings suggest that ALD is associated with early and progressive neuroretinal degeneration, distinct from the typical pattern seen in glaucomatous optic neuropathy, and highlight the potential role of spectral-domain optical coherence tomography as a non-invasive tool for detecting subclinical neuroretinal damage in patients with ALD.
