1 · What the graph read from it

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.

2 · The registry

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 aimed to evaluate the early effects of a comprehensive redevelopment of a low-income, minority community on adult obesity.

methodsWe analyzed longitudinal data on a cohort of public housing residents from Jordan Downs (JD), the community undergoing redevelopment, and a comparison group in Watts, Los Angeles, California. Difference-in-difference models with individual fixed effects were estimated on a sample of 421 adults comparing changes in BMI and waist circumference for JD versus comparison group residents between baseline (2018-2019) and follow-up (2021-2022). Quasi-experimental variation in redevelopment exposure was used to assess dose-response relationships. Secondary outcomes included diet and physical activity barriers and behaviors.

resultsThere were no significant differences in BMI or waist circumference changes between JD residents (n = 279) and the comparison group (n = 149) overall. Within JD, those who moved to redeveloped areas (n = 75) experienced a 2.2% larger reduction in waist circumference (95% CI: -0.05 to -0.003) and a 10.6 percentage point (95% CI: -0.20 to -0.02) greater decline in abdominal obesity, relative to the comparison group. They reported greater declines in barriers to healthy eating and exercise, along with reduced added sugar intake, but no differential changes in BMI, obesity, physical activity, or diet quality.

conclusionsRedeveloping low-income communities can reduce abdominal obesity.
