Quantifying the link: coronary artery inflammation via CCTA-derived fat attenuation index and its association with diabetes duration.

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
Aims: Although diabetes is a well-established enhancer of coronary inflammation, the specific relationship between diabetes duration and the degree of inflammation, as quantified by pericoronary fat attenuation index (FAI), remains poorly defined. This study aimed to investigate the association between diabetes duration and coronary inflammation, as assessed non-invasively by the pericoronary FAI derived from coronary computed tomography angiography (CCTA). Materials and methods: We enrolled 468 adults with type 2 diabetes mellitus who underwent CCTA imaging. The pericoronary FAI was quantified around the three main coronary arteries. Multivariablee association between diabetes duration and pericoronary FAI. Potential non-linear associations were examined using restricted cubic spline (RCS) modelling. Results: Longer diabetes duration was independently and positively associated with increased pericoronary FAI values in the LAD artery (β = 0.151, 95% CI: 0.064-0.238, P = 0.001), LCX artery (β = 0.101, 95% CI: 0.001-0.201, P = 0.047), and RCA (β = 0.208, 95% CI: 0.120-0.296, P < 0.001). RCS modelling revealed predominantly linear associations(P for non-linearity > 0.05). The association between diabetes duration and pericoronary FAI remained robust across the majority of examined subgroups. Conclusion: Prolonged diabetes duration is independently associated with elevated coronary inflammation, demonstrating a near-linear dose-response relationship.
