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

backgroundObesity, a chronic disease characterized by pathological fat accumulation, requires effective therapeutic strategies. While sleeve gastrectomy (SG) demonstrates superior efficacy for sustained weight loss, clinical guidelines lack integration of objective body composition metrics used in chronic disease management. This study aims to investigate the relationship between preoperative body composition and postoperative weight loss outcomes in patients undergoing SG.

methodsPatients with obesity who underwent SG at our center between October 2019 and May 2024 were enrolled. Preoperative body composition was assessed using abdominal computed tomography (CT) and bioelectrical impedance analysis (BIA). Weight loss outcomes were evaluated using body mass index (BMI), percentage of excess weight loss (%EWL), and percentage of total weight loss (%TWL). Regression and receiver operating characteristic (ROC) analyses were performed to identify predictors of surgical success.

resultsIn a study of 315 individuals (63.5% female). CT analysis showed that males had significantly higher core muscle mass, including psoas major index (10.71 ± 2.35 vs. 7.12 ± 1.54 cm

conclusionPreoperative body composition, particularly core muscle mass and subcutaneous fat distribution, is strongly associated with postoperative weight loss outcomes after SG. CT-based assessments may offer valuable prognostic insight predict surgical outcomes and adjust interventions accordingly.
