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

objectiveThe aim of this study is to examine whether school food attenuates household income-related disparities in adolescents' frequency of fruit and vegetable intake (FVI).

methodTelephone surveys were conducted between 2007 and 2008 with adolescent-parent dyads from Northern New England; participants were randomly assigned to be surveyed at different times throughout the year. The main analysis comprised 1542 adolescents who typically obtained breakfast/lunch at school at least once/week. FVI was measured using 7-day recall of the number of times adolescents consumed fruits and vegetables. Fully adjusted linear regression was used to compare FVI among adolescents who were surveyed while school was in session (currently exposed to school food) to those who were surveyed when school was not in session (currently unexposed to school food).

resultsMean FVI was 8.0 (SD=5.9) times/week. Among adolescents unexposed to school food, household income and FVI were strongly, positively associated. In contrast, among adolescents exposed to school food, FVI was similar across all income categories. We found a significant cross-over interaction between school food and household income in which consuming food at school was associated with higher FVI among adolescents from low-income households versus lower FVI among adolescents from high-income households.

conclusionSchool food may mitigate income disparities in adolescent FVI. The findings suggest that the school food environment positively influences FVI among low-income adolescents.
