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
introductionFood policies and standards regulate school meal equity and quality, yet there is a complex system involved in translating and implementing these standards. To catalyze systems-level thinking in school meals, stakeholders across the supply chain were asked to collaborate in examining the role of dairy as representative of broader food system opportunities and challenges in California school meals.
methodsThis descriptive case study applied the What, So What, Now What reflective framework, 19 phone interviews of school nutrition directors and dairy processors, conducted from August to September 2024, logged current practices, infrastructures, supports and insights. Results informed an in-person convening of 40 supply chain stakeholders in January 2025. At the convening, three presentations, four themed small-group dialogues and a strategic planning session sought options for improving student wellness by modifying the school meal system.
resultsInterviews focused on the "what," gathering facts about procurement, nutrition and policy compliance challenges. Convening dialogues focused on the "so what," making meaning of the challenges and expanding knowledge on dairy innovation and the future of school meals from different perspectives across the supply chain. The strategic planning session (the "now what") revealed opportunities that were shaped into actionable next steps emphasizing farm-to-cafeteria nutrition education, incorporating a wider cultural variety of dairy foods and activating local food system partnerships and professional development across the food supply chain. DISCUSSION: Collaboration and structured systems thinking identified next steps for dairy that support the supply chain from processors to foodservice professionals to student consumers. Using a systems thinking framework allowed stakeholders to understand the issues more objectively, consider different perspectives and identify actionable solutions. Outcomes also suggest supply chain collaboration can be a replicable blueprint for troubleshooting other institutional food systems.
