Association of Attenuated Plaques Detected by Intravascular Ultrasound With Plaque Calcification Assessed by Computed Tomography Angiography.
Article in Reviews in cardiovascular medicine, 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
Background: Coronary artery calcium (CAC) reflects the overall atherosclerotic burden. The CAC density is inversely associated with plaque vulnerability. Intravascular ultrasound (IVUS)-defined attenuated plaques represent unstable lesions, which are linked to adverse clinical outcomes. Meanwhile, the determination as to whether coronary computed tomography angiography (CCTA)-derived CAC metrics can serve as noninvasive markers of attenuated plaques remains uncertain. Methods: This retrospective study included coronary artery disease (CAD) patients who underwent both CCTA and IVUS between January 2023 and December 2024 at our medical center. CCTA was used to quantify plaque volume, density, and composition (lipid, fiber, and calcium), while IVUS was employed to characterize the plaques as attenuated and non-attenuated. Results: Among 94 patients with 150 coronary plaques, calcium volume showed a very strong correlation with total plaque volume ( Conclusion: CCTA-derived CAC volume reflects the atherosclerosis (AS) burden, while lower CAC density independently predicts IVUS-confirmed attenuated plaques. A higher CAC density was associated with plaque stability, suggesting that the CCTA-derived CAC density may serve as a noninvasive marker of plaque stability, aiding in the assessment of plaque vulnerability and risk stratification.
