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

backgroundOur objective was to examine the association between school wellness committees and implementation of nutrition wellness policies and children's weight status and obesity-related dietary outcomes.

methodsA cross-sectional study was conducted of 4790 children aged 4-15 years recruited from 130 communities in the Healthy Communities Study. Multilevel statistical models assessed associations between school wellness policies and anthropometric (body mass index z-score [BMIz]) and nutrition measures, adjusting for child and community-level covariates.

resultsChildren had lower BMI z-scores (-0.11, 95% confidence interval [CI]: -0.19, -0.03) and ate breakfast more frequently (0.14 days/week, 95% CI: 0.02-0.25) if attending a school with a wellness committee that met once or more in the past year compared to attending a school with a wellness committee that did not meet/did not exist. Children had lower added sugar (p < .0001), lower energy-dense foods (p = .0004), lower sugar intake from sugar-sweetened beverages (p = .0002), and lower dairy consumption (p = .001) if attending a school with similar or stronger implementation of the nutrition components of the school wellness policies compared to other schools in the district.

conclusionsA more active wellness committee was associated with lower BMI z-scores in US schoolchildren. Active school engagement in wellness policy implementation appears to play a positive role in efforts to reduce childhood obesity.
