Neighborhood-Level Variation in the Effectiveness of Intensive Health Behavior and Lifestyle Treatment for Pediatric Obesity.
Article in Obesity (Silver Spring, Md.), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveThis study assessed variation in BMI change by neighborhood characteristics of participants in Bright Bodies, a family-based intensive health behavior and lifestyle treatment for pediatric obesity.
methodsFor first-time participants (2008-2018) with initial BMI ≥ 85th percentile, we geocoded addresses and assigned Child Opportunity Index (COI) and COI-Healthy Environment (COI-HE) scores (Low/Moderate/High). Using multivariable mixed effect linear regression, we assessed monthly change in BMI percent of the 95th percentile (%BMIp95) and extended BMI z score by COI and COI-HE.
resultsOf 391 youth (mean ± SD age 11.7 ± 2.8 years, 60.1% female), 80.8% resided in Low COI and 66.5% in Low COI-HE neighborhoods. Monthly %BMIp95 change differed by COI (p = 0.039 for interaction) and COI-HE (p = 0.004). Mean %BMIp95 decreased in all subgroups; greatest reductions were in High COI (-1.86 [95% CI: -2.40, -1.33]) and High COI-HE groups (-2.32 [-2.78, -1.85]) and lowest in Moderate COI (-1.17 [-1.59, -0.75]) and Low COI-HE groups (-1.53 [-1.75, -1.32]). Change in extended BMI z score differed significantly between COI-HE subgroups only (p < 0.001).
conclusionsBright Bodies participation was associated with BMI reduction among all COI/COI-HE subgroups, but the highest COI/COI-HE groups had the greatest reductions. Modifications to intensive health behavior and lifestyle treatments should address inequities in access to built environments that facilitate healthy, active living.
