Understanding regional disparities in obesity: a multiscale geographically weighted analysis in the United States.
Article in International journal of health geographics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Obesity varies markedly across U.S. counties, and global models often miss place-specific determinants. While prior studies document higher prevalence in nonmetropolitan areas, the geographic variation in its determinants-known as spatial heterogeneity-remains underexplored. We linked age-adjusted adult obesity prevalence with socioeconomic indicators, and behavioral risks for 3106 contiguous counties. A global OLS model served as a baseline, followed by estimation of Multiscale Geographically Weighted Regression (MGWR). MGWR outperformed global OLS (adjusted [Formula: see text]: 0.801 vs. 0.566; AICc: 13,580.92 vs. 15,764.21), confirming non-stationarity and revealing covariate-specific scales. Metropolitan status was generally protective, but its effect attenuated or reversed in parts of the West. Income and educational attainment are broadly inverse with minimal dispersion across counties, suggesting near-global behavior in this specification. Short sleep shows a strong positive association with little spread, while binge drinking is positive and slightly more variable. Employment is narrowly positive with almost no spatial dispersion. Bandwidth diagnostics separate near-global from local processes: metro and employment operate at large bandwidths, education and binge drinking at meso scales, and income, short sleep, and marriage at finer scales. As a benchmark, metro-only models showed a uniformly protective but locally varying metro effect that attenuated once socioeconomic and behavioral covariates were included. Findings confirm non-stationarity and argue for a two-tier translation: system-level policies for near-global factors and community-tailored interventions for localized risks, with attention to Western metropolitan vulnerabilities and Southeastern rural constraints.
