1 · What the graph read from it

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.

2 · The registry

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 contrast retinal and choroidal vascular alterations between carotid artery dissection (CAD) and carotid artery stenosis (CAS), and analyze their associations with cerebral infarction patterns and stenosis severity.

methodsThis observational study included stenotic-degree-matched patients with CAD and patients with CAS. Retinal ischemic signs-cotton wool spots, retinal artery occlusion, and paracentral acute middle maculopathy-were evaluated using fovea-centered optical coherence tomography/angiography. Retinal vascular density and choroidal metrics (choriocapillaris density, thickness, vascular volume, and index) were analyzed.

resultsThe final analysis included 863 eyes from 467 participants (85 with CAD, 274 with CAS, 108 controls). Patients with CAD showed a significantly higher prevalence of paracentral acute middle maculopathy than Patients with CAS (6.4% versus 0.61%,

conclusionsCompared with atherosclerotic stenosis, CAD exhibits a distinct oculovascular phenotype characterized by a higher burden of acute retinal ischemia but compensatory choroidal hyperperfusion. Retinal imaging serves as a noninvasive window into CAD pathophysiology, offering biomarkers for assessing hemodynamic stability and thromboembolic risk.
