1 · What the graph read from it

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.

2 · The registry

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: Obesity is associated with structural and functional cardiac remodeling; however, its quantitative imaging characteristics and the role of left ventricular trabeculation remain incompletely understood. This study aimed to characterize left ventricular trabeculation using multi-parametric cardiac magnetic resonance in patients with obesity, explore its association with subclinical cardiac dysfunction, and evaluate longitudinal changes following bariatric surgery. Methods: In this prospective single-center study, 30 patients with severe obesity underwent cardiac magnetic resonance imaging before and approximately 12 months after bariatric surgery, along with 30 age- and sex-matched healthy controls. Quantitative parameters included the non-compacted to compacted layer ratio (NC/C), trabecular mass fraction, left ventricular mass, left ventricular ejection fraction, global longitudinal strain, and diastolic filling indices. Left ventricular ejection fraction indexed to body surface area was analyzed as an exploratory parameter. Mediation analysis was performed to assess whether trabeculation statistically explained part of the association between body mass index and cardiac function, adjusting for age, sex, and blood pressure. Results: Compared with controls, patients with obesity showed significantly higher NC/C (1.68±0.24 Conclusions: Quantitative cardiac magnetic resonance analysis demonstrates increased left ventricular trabeculation in obesity, which decreases following weight reduction. Trabeculation is associated with subclinical cardiac dysfunction and may contribute to the association between obesity and impaired cardiac function. These findings suggest that trabecular remodeling in obesity represents a dynamic imaging phenotype, although further studies are required to clarify underlying mechanisms.
