Associations between obesity and arterial stiffness assessed by cardio-ankle vascular index in healthy children and adolescents.

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
Aims: Cardio-ankle vascular index (CAVI) is a non-invasive method for evaluating arterial stiffness. In adults, CAVI has been reported to show negative correlation with body mass index (BMI) known as the "obesity paradox"; however, whether this also applies to children remains unclear. In addition, childhood obesity is a problem in developed countries, and the utility of CAVI in children has not yet been clarified. We here aimed to clarify the relationship between obesity parameters and CAVI in healthy children. Methods: This was a cross-sectional study conducted in 2024. We evaluated CAVI and its associated factors in 590 children aged 6-15 years (mean age: 10.5 years, 51.0% female). Additionally, obesity parameters, including the Rohrer index, percentage of overweight (POW), body fat percentage and body fat mass determined by bioelectrical impedance analysis, and BMI were assessed. The participants were categorized into groups based on the obesity parameters. Results: CAVI decreased as obesity level increased, showing the lowest CAVI in the highest obesity category. CAVI was positively correlated with age ( Conclusion: Obesity parameters are negatively and independently associated with CAVI in healthy children.
