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

Aims: Atrial myopathy encompasses structural, functional, electrical, and metabolic changes in the atrial myocardium. While remodelling such as left atrial (LA) dilation and reduced strain are well documented, metabolic alterations remain underexplored. 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) provides a non-invasive tool to assess myocardial glucose metabolism. This study evaluates the relationship between atrial FDG avidity and LA remodelling in patients undergoing cardiac imaging for suspected cardiac sarcoidosis (CS). Methods and results: We studied 120 patients who underwent both cardiac MRI and FDG-PET/CT at the University of Washington Medical Center. LA structural volume index (LAVi) and functional emptying fraction (LAEF), average long-axis strain, and phasic strain indices were derived from cine MRI using feature tracking. Atrial FDG avidity was quantified by SUVmax and atrial target-to-background ratio (aTBR) from PET/CT. LA average long axis strain was 37.1 ± 34.0%, LAEF 47.6 ± 16.1%, and LAVi 36.0 ± 23.0%. Atrial avidity was 2.4 ± 0.7 SUV. LA strain negatively and mildy correlated with both SUVmax ( Conclusion: Increased atrial FDG avidity is independently associated with impaired strain and enlarged LA, highlighting a metabolic component of atrial myopathy that may precede clinical AF.
