Assessing nutritional compliance, plate waste and menu acceptability in Spanish school meal programmes (ANPAS-Sp): protocol for an explanatory sequential mixed methods study.
Article in MethodsX, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The implementation of healthy, sustainable school menus represents a critical transition requiring strategic management to ensure nutritional compliance, student acceptability, and minimal food waste. Currently, evidence remains inconsistent due to a lack of validated protocols correlating nutritional standards with objective consumption data. Consequently, a comprehensive, explanatory sequential mixed-methods protocol is developed (ANPAS-Sp). It integrates a systematic nutritional audit (Phase 1) -aligned with Spain's Real Decreto 315/2025 and Catalonia's School Menu Review Programme-with high-precision direct weighing of plate waste and validated facial hedonic scales (Phase 2). Furthermore, the protocol employs targeted focus groups to qualitatively explore food rejection patterns identified after quantitative phase (Phase 3). This protocol facilitates evidence-based interventions and data pooling to advance sustainable school food systems. It spearheads a standardized evaluation framework for public health policies, establishing a new benchmark for gathering integrated evidence. Ultimately, this approach provides the necessary tools to transform school meal programs into healthy, widely-accepted, and zero-waste systems.•Approach: A standardised evaluation framework that empirically correlates the compliance of nutritional recommendations, the quantification of plate waste, and student acceptability of school meals.•Impact: It provides the necessary scientific tools to optimise school meal programmes and promote the transition towards sustainable school food systems.
