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

backgroundPatients with severe obesity exhibit a significant accumulation of epicardial adipose tissue (EAT) and mediastinal fat (MF). Although the accumulation of EAT has been reported to cause diastolic dysfunction owing to constrictive pericardial effects, the effect of MF on cardiac function remains unclear. The reduction of thoracic adipose tissue, including EAT and MF, may lead to improved cardiac function. The aim of the present study is to evaluate the effects of changes in EAT and MF on cardiac function after metabolic and bariatric surgery (MBS) on cardiac function.

methodsWe retrospectively evaluated the data of 75 patients who underwent laparoscopic sleeve gastrectomy (LSG) at a single institution. EAT and MF measurements and cardiac ultrasonography were performed at the initial visit and 1 year after LSG, and the relationships between changes in EAT and MF with cardiac function were investigated.

resultsAfter LSG, EAT and MF significantly decreased (p < 0.001). Eight patients had diastolic dysfunction, and the improvement rate in diastolic dysfunction after LSG was 62.5%. Patients with diastolic dysfunction also had a greater accumulation of EAT than patients with normal diastolic function (74.6 vs. 102.2 mL, p = 0.041), along with a significantly greater rate of change in EAT after LSG (23.8% vs. 33.6%, p = 0.034). Univariate analysis results after propensity score (PS) matching also showed significantly greater EAT at the baseline in patients with diastolic dysfunction and indeterminate patients(69.8 vs. 102.2 mL, p = 0.034). Multivariate analysis results after PS matching showed that EAT accumulation at baseline may be an independent factor for diastolic dysfunction (odds ratio, 1.023; 95% confidence interval 1.000-1.054, p = 0.049), and the rate of change in EAT (odds ratio, 1.157; 95% confidence interval 1.029-1.435, p = 0.061) after MBS may also be independent factors.

conclusionsIn patients with severe obesity and diastolic dysfunction, EAT accumulation may exert significant pericardial constrictive effects. Furthermore, EAT significantly reduced after LSG, contributing to improved diastolic dysfunction.
