Outcomes of Carotid Artery Stenting without Embolic Protection in Yemen: A Resource-Constrained Experience.
Article in Journal of neuroendovascular therapy, 2025. 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
Objective: Carotid artery stenting (CAS) has been reported to be a safe and effective option for treating carotid atherosclerotic disease. However, reports and studies from resource-limited countries are scarce. The published data support the use of embolic protection devices (EPDs) to reduce periprocedural stroke. This study aimed to evaluate the outcomes of CAS procedures without EPDs in Yemen, one of the lowest-income countries. Methods: This is a retrospective cohort study regarding CAS for symptomatic carotid artery stenosis that was conducted at the stroke center of Borg Al-Atiba and American Modern Hospital during the period from March 2023 to March 2025. All patients with symptomatic carotid artery stenosis were included in the study. CAS procedures were performed by a single interventional neurologist. The primary outcomes included a 30-day periprocedural mortality, stroke, myocardial infarction, or arrhythmia. Any other complications were considered secondary outcomes. Results: A total of 62 patients (53 males) were included in this study, with a mean age of 60.2 ± 9.7 years. All patients had symptomatic carotid artery stenosis. The technical success rate was 100%. No perioperative cerebral infarctions were observed. One patient developed transient dysarthria, but diffusion-weighted-MRI was negative. Significant bradycardia occurred in 2 patients and responded immediately to atropine. Three patients developed mild local hematoma, and 1 patient had a femoral pseudoaneurysm. Closed-cell Carotid WALLSTENT (Boston Scientific, Marlborough, MA, USA) was used as a single stent in all patients. Conclusion: CAS conducted by a trained interventional neurologist without EPDs demonstrates a low complication rate, and it is an effective and safe option in countries with limited resources.
