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

backgroundIn 2012, Massachusetts implemented both the updated national school meal standards and comprehensive competitive food/beverage standards that closely align with current national requirements for school snacks.

objectivesThis study examines the impact of these combined standards on school meal and snack food selections, as well as food choices outside of school. In addition, this study examines the impact of these standards on nutrients consumed.

designThe NOURISH (Nutrition Opportunities to Understand Reforms Involving Student Health) Study was an observational cohort study conducted among students from spring 2012 to spring 2013. PARTICIPANTS/

settingOne hundred sixty students in 12 middle schools and high schools in Massachusetts completed two 24-hour recalls before (spring 2012) and after implementation (spring 2013) of the updated standards.

main outcome measuresChanges in school meals, competitive food, and after-school snack selection, as well as nutrients consumed outside of school were examined. STATISTICAL ANALYSES PERFORMED: Logistic regression and mixed-model analysis of variance were used to examine food selection and consumption.

resultsAfter implementation, 13.6% more students chose a school meal (70.1% vs 56.5%; P=0.02). There were no differences in competitive food purchases but a significant decrease in the number of after-school unhealthy snacks consumed (0.69 [standard error=0.08] vs 1.02 [standard error=0.10]; P=0.009). During the entire day, students consumed, on average, 22 fewer grams of sugar daily after implementation compared with before implementation (86 g vs 108 g; P=0.002).

conclusionsWith the reduction in the number of unhealthy school snacks, significantly more students selected school meals. Students did not compensate for lack of unhealthy snacks in school by increased consumption of unhealthy snacks outside of school. This provides important new evidence that both national school meal and snack policies may improve daily diet quality and should remain strong.
