Association between visceral adiposity index and chronic obstructive pulmonary disease: A cross-sectional analysis.
Article in Science progress. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
BackgroundPrevious studies suggest that obesity may exacerbate clinical manifestations of chronic obstructive pulmonary disease (COPD). Early detection of COPD could improve therapeutic outcomes. This study investigates the relationship between a novel metabolic biomarker, the Visceral Adiposity Index (VAI), and COPD risk. We hypothesized that higher VAI levels would be independently associated with an increased prevalence of COPD.MethodsThis study is a cross-sectional analysis of data from the National Health and Nutrition Examination Survey (NHANES) spanning the periods 1999-2018 and 2021-2023. Multivariable logistic regression was employed to assess the association between VAI and COPD, supplemented by subgroup stratification, smoothed curve fitting, and threshold effect analyses.ResultsAmong 16,167 participants, 1397 were diagnosed with COPD. Multivariable logistic regression revealed a positive correlation between VAI levels and COPD prevalence, independent of confounding factors. Subgroup analyses indicated stronger associations in hypertensive patients and females. Smoothed curve fitting identified a threshold effect for VAI, with an inflection point at 2.55 (P = 0.002).ConclusionThe findings of this study indicate a significant positive correlation between VAI levels and the prevalence of COPD. Maybe incorporating visceral adipose function assessment into the initial risk stratification system for high-risk populations with COPD holds certain clinical value.
