Efficacy of a school-based obesity prevention intervention at reducing added sugar and sodium in children's school lunches: the LA Health randomized controlled trial.
Trial report in International journal of obesity (2005), 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
backgroundDecreasing selection and consumption of sodium and added sugars in the school cafeteria setting is important to provide optimal nutrition to children.
objectiveThe ofjective of this study is to determine whether Louisiana (LA) Health, a school-based obesity prevention intervention, could successfully reduce children's selection and consumption of sodium and added sugars during school lunches vs. the control group.
designFood selection, consumption, and plate waste from student lunches (3 consecutive days) in 33 public schools in rural Louisiana were collected and analyzed using the digital photography of foods method at baseline and after a 28-month obesity prevention intervention (LA Health) beginning in 4th-6th grade (87% of children received free or reduced cost lunch). Selection and consumption of energy, added sugar, and sodium was objectively measured using digital photography of foods. Mixed models, including Race and BMI, were used to determine whether change in selection and consumption differed by group.
resultsSodium decreased for selection (- 233.1 ± 89.4 mg/lunch, p = 0.04) and consumption (- 206.3 ± 65.9, mg/lunch) in the intervention (vs. control) by month 18, and in consumption by month 28 (- 153.5 ± 66.9 mg/lunch, p = 0.03). Change in added sugar consumption decreased in the intervention (vs. control) at month 18 (- 3.7 ± 1.6, p = 0.05) and at month 28 (- 3.5 ± 1.6 tsp/lunch, p = 0.05).
conclusionsLA Health decreased the amount of added sugar and sodium selected and consumed, but not plate waste, by month 28. Results highlight the importance of long-term interventions and policies targeting provision and selection to improve dietary patterns in children, with less focus on plate waste.
