Study on the correlation between carotid plaque calcification types and the recurrence of ischemic stroke.
Article in BMC medical imaging, 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
objectiveTo investigate the correlation between carotid plaque calcification types and recurrent stroke using computed tomography angiography (CTA). Additionally, a conjoint analysis was conducted to explore the physical activity, appetite, sleep, and mood of the patients as variables, to provide a novel reference for the clinical treatment and management of ischemic stroke.
methodPatients who underwent head and neck CTA scans and were diagnosed with unilateral or bilateral carotid plaques with stenosis < 70% at the First People’s Hospital of Lianyungang from September 2022 to August 2023 were enrolled in this study. They underwent 2 to 3 years of follow-up. Patients meeting the inclusion criteria were classified into 1 to 6 types based on plaque calcification characteristics, to analyze differences in recurrent stroke between these types.
resultsUsing the eligibility criteria, 346 patients with carotid plaque were included. In the clinical baseline data, no significant differences were observed between the recurrent and the non-recurrent stroke groups. Spearman’s correlation analysis showed significant associations between plaque calcification types and recurrent stroke (p < 0.001). Subsequently, Cox proportional hazards model analysis further demonstrated a significant correlation between plaque calcification types and clinical endpoint (HR: 1.149,95% CI: 1.059–1.247, p < 0.001). Even after adjusting for sleep, appetite, physical activity, and mood of the patients, the plaque calcification types remained significantly associated with the clinical endpoint (HR: 1.128,95% CI: 1.037–1.226, p = 0.005).
conclusionThis study indicates a correlation between carotid plaque calcification types and the recurrence of stroke. These findings provide a novel approach to reviewing carotid atherosclerotic plaque calcification and further imaging-based evidence for the risk assessment of recurrent ischemic stroke.
