Relation of Perivascular Adipose Tissues on Computed Tomography to Coronary Vasospasm.
Article in Reviews in cardiovascular medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 computed tomography angiography (CTA) can be used to quantitatively and qualitatively evaluate the characteristics of perivascular adipose tissue (PVAT), including PVAT volume and perivascular fat attenuation index (FAI). Moreover, PVAT volume and perivascular FAI on CTA are reportedly high in patients with vasospastic angina (VSA); however, previous investigations have focused on the patient rather than vessel-level analyses. Therefore, this study aimed to assess the relationship between coronary vasospasm and PVAT or FAI by using coronary CTA at the vessel level. Methods: This retrospective study included 51 patients who underwent intracoronary acetylcholine (ACh) provocation testing for the VSA diagnosis and coronary CTA within a 6-month interval. A total of 125 coronary vessels were evaluated. PVAT and FAI on CTA were quantitatively evaluated. The primary interest of the present study was to determine the relationship between PVAT volume and FAI- and ACh-induced coronary vasospasms at the vessel level. Results: Of the 51 patients, 24 (47.1%) had a positive ACh provocation test (VSA), with 40 of 125 (32.0%) vessels having ACh-induced vasospasm. Obstructive epicardial coronary artery disease was observed in 12 vessels (9.6%). No significant differences in PVAT volume or FAI were identified between vessels with and without ACh-induced vasospasms. Similarly, PVAT volume and FAI did not differ significantly in the individual major coronary arteries between patients with and without positive ACh provocation test results. In contrast, FAI was significantly higher in vessels with obstructive coronary artery disease than in those without. Conclusions: In patients undergoing intracoronary ACh provocation tests and coronary CTA, no significant association was observed between ACh-induced coronary vasospasm and PVAT volume or FAI at the vessel level. However, FAI significantly increased in vessels with epicardial coronary disease.
