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

introductionCurrently, the interaction between heart failure with preserved ejection fraction (HFpEF) and obesity is discussed. As part of a complex echocardiographic examination, the two-dimensional speckle tracking (2D-STE) method is a significant tool for assessing dysfunction of the left atrium. Our study aimed to compare left atrial function using the 2D-STE in patients with class III obesity and a control group.

methodsThis was an observational, prospective, pilot /preliminary/ study that enrolled 20 patients with class III obesity (Body mass index (BMI) > 40 kg/m²) and a group of nineteen healthy individuals with a BMI of 20–25 kg/m² as controls. The following parameters were observed: Reservoir Left Atrial Strain (R-LAS), Conduit Time (CT-LAS), and Contractile Displacement (CD-LAS).

resultsThe study patient group included sixteen women and four men (average age 42.4 years, ranging 19–63). The mean BMI was 47.69 ± 8.86 kg/m². The control group was created from fifteen women and four men (average age 27.2 ± 3.7 years, average BMI 22.48 kg/m²). The study found significant differences in R-LAS (29.9 ± 7.0 vs. 45.0 ± 11.7;p < 0.001) and CT-LAS (-16.8 ± 5.89 vs. -29.7 ± 8.71;p < 0.001) between patients with class III obesity and controls. No significant difference was seen in the remaining studied parameter /CD-LAS/ (-13.2 ± 4.77 vs. -15.1 ± 6.28;p = 0.305).

conclusionThe R-LAS and CT-LAS were significantly changed (reduced) in patients with class III obesity compared to the controls.
