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

backgroundThe Supplementary Nutrition Assistance Program (SNAP) is a critical lifeline for millions of low-income US families, but some studies suggests that it may inadvertently increase obesity risk. Building on research contesting the SNAP-obesity link, we examine the effect of SNAP participation on BMI among multiyear participants at varying levels of SNAP benefit levels to provide some of the first evidence on the relationship between SNAP participation, state-level SNAP resources, and body weight. We focus on children given the strong links between early-life obesity and later-life health.

methodsLinking state-level data on SNAP benefit levels with three waves of longitudinal individual-level data from the Child Development Supplement of the Panel Study of Income Dynamics, we use child- and state-level fixed effects to examine whether exogenous differences in SNAP benefit allotments influence the relationship between SNAP participation and weight gain.

resultsLower SNAP benefit levels were associated with only modest increases in BMI among children; higher benefit levels showed no association with BMI.

conclusionsAlthough concerns that more food assistance promotes obesity have spurred calls for cuts in the SNAP program, we find the opposite - that SNAP participation is associated with an increase in childhood BMI only when benefit levels are low. This study adds to the mounting evidence suggesting that SNAP does not cause obesity. It also contributes to the literature on the political economy of health, especially that pertaining to social policy variation across US states.
