Development and Validation of a Technology-Based System for Tracking and Reporting Dietary Intake at School Meals.
Article in Journal of nutrition education and behavior, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveThis report describes the development and validation of a technology-based system that integrates data on food choice, nutrition, and plate waste to generate feedback reports summarizing students' dietary intake at school meals.
methodsCafeteria staff used the system to document the school lunch choices of seventh-graders (n = 37) in an urban charter school for 5 months. Plate waste was assessed by research staff using a visual estimation method that was validated against directly weighed plate waste.
resultsMost food choices (97.1%) were correctly recorded through the system. Visual estimates of plate waste had excellent interrater reliability (r's ≥ .94) and agreement with direct measurements (ρ's ≥ .75). Plate waste assessment required approximately 10 s/tray. Fifty-four percent of parents received feedback reports consistently. CONCLUSIONS AND IMPLICATIONS: The technology-based system enabled staff to monitor dietary intake accurately at school meals. The system could potentially inform lunch menu modifications aimed at reducing plate waste.
