Application of Epicardial Fat Volume for Identifying Hemodynamically Significant Coronary Artery Disease: A Retrospective Study.
Article in International journal of general 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: With the widespread application of coronary computed tomography angiography (CCTA), exploring novel biomarkers in imaging data to optimize the risk stratification of hemodynamically significant coronary artery disease (HS-CAD) has become a research hotspot. HS-CAD was defined as ≥50% stenosis on CCTA with a corresponding reversible perfusion defect on single-photon emission computed tomography myocardial perfusion imaging (SPECT-MPI). Although coronary artery calcium score (CACS) is routinely used, it is difficult to fully reflect the biological activity and functional impact of plaques. This single-center retrospective study aimed to investigate the association between epicardial fat volume (EFV) and HS-CAD, and to evaluate its incremental diagnostic value over clinical risk factors and the CACS. Methods: A single-center retrospective study included 140 patients who underwent both CCTA and SPECT-MPI. EFV and CACS were quantitatively assessed. Univariable and multivariable logistic regression analyses were performed to identify independent predictors. Results: Among the included patients, 50 (35.7%) had HS-CAD. The HS-CAD group had a higher prevalence of smoking and significantly greater EFV and CACS (all P<0.05). Multivariable analysis identified smoking history (OR=5.79;95% CI:2.14-15.66; indicating that smokers had nearly 6-fold higher odds of HS-CAD), CACS (OR=1.91 per 100-unit increase;95% CI:1.35-2.70), and EFV (OR=1.04 per cm Conclusion: EFV is independently associated with HS-CAD and provides incremental diagnostic value over clinical risk factors and CACS in this single-center retrospective study. These findings suggest that EFV may serve as a valuable biomarker for improving non-invasive risk stratification, warranting prospective validation in multicenter studies.
