Visceral-to-subcutaneous fat ratio and risk of gallstones in Korean men: an observational study of 4,914 cases.

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.
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
Introduction: Gallstones are a prevalent gastrointestinal disorder influenced by metabolic factors and obesity. Visceral adiposity is metabolically active and proinflammatory, yet the role of the relative distribution of visceral and subcutaneous fat, quantified as the visceral-to-subcutaneous fat ratio (VSR), in gallstone formation remains unclear. This study aimed to investigate the association between VSR, measured by computed tomography (CT), and the prevalence of gallstones in Korean men. Methods: This retrospective cross-sectional study included 4,914 Korean men who underwent both abdominopelvic CT and ultrasonography as part of routine health examinations. Visceral and subcutaneous fat areas were quantified at the L3 vertebral level using CT images, and participants were categorized into quartiles based on the VSR. Logistic regression analyses were conducted to evaluate the association between VSR and the prevalence of gallstones, adjusting for age, body mass index (BMI), lifestyle factors, comorbidities, and biochemical markers. Results: The mean age and BMI were 52.3 ± 9.3 years and 24.6 ± 2.9 kg/m Conclusion: A higher VSR, reflecting a predominance of visceral over subcutaneous fat, was independently associated with an increased risk of gallstones in Korean men. These findings highlight the importance of abdominal fat distribution, beyond overall obesity, in gallstone pathogenesis. The VSR may serve as a valuable imaging biomarker for identifying men at elevated risk of developing gallstones.
