Association of retinal microvascular abnormalities with cardiovascular diseases in patients with severe carotid artery stenosis.
Observational study in International journal of medical sciences, 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
Purpose: To investigate and summarize the characteristics of retinal microvascular abnormalities (RMAs) in patients with severe carotid artery stenosis (CAS) and explore the association between the presence of RMAs and cardiovascular diseases (CVD). Methods: Color fundus photography and wide-field swept-source optical coherence tomography angiography (SS-OCTA) examinations were performed on all participants. Images were reviewed to identify RMAs. The occurrence and characteristics of RMAs were summarized. CAS patients with or without CVD were divided into different groups, and the association between the presence of RMAs and CVD were explored using multivariable logistic regression analysis. Results: This observational, cross-sectional study included 258 eyes from 129 patients with severe CAS. A total of 39/129 patients (30.2%) were identified with RMAs. These RMAs included branch retinal artery occlusion, asymptomatic retinal emboli, cotton wool spots, retinal hemorrhage, branch retinal vein occlusion, inner retinal layer hyperreflectivity, retinal nonperfusion and neovascularization of the optic disk. Multivariable logistic regression analysis revealed that RMAs was significantly associated with the presence of CVD in patients with severe CAS. Conclusions: This cross-sectional study summarized the characteristics of RMAs associated with CAS and identified RMAs as biomarkers of CVD in patients with severe CAS. Patients with RMAs were at high risk and should be carefully managed.
