Structures and systems that promote nutrition security and climate adaptation in Puerto Rico: results from community-based system dynamics.
Article in Public health nutrition, 2025. 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
objectiveThis study aimed to develop a shared understanding about the drivers of nutrition security in Puerto Rico (PR) from the collective perspective of multi-sector stakeholders in the agri-food, environmental and the health/disease systems.
designA participatory community-based system dynamics approach (group model building) engaged stakeholders during one 4-h workshop March 2023 (followed by two 2.5-h member checking sessions).
settingSan Juan, PR.
participantsStakeholders (
resultsStakeholders collectively framed nutrition security as an outcome of six interconnected subsystems exacerbated by climate change: (1) governance and public policy; (2) demographic change and rural disinvestment; (3) climate change and adaptive capacity; (4) local food production economy; (5) food culture; and (6) nutrition security and health. Stakeholders identified leverage points mostly focused on strengthening information flow within and across subsystems and expanding cross-sectoral collaboration (systems structures and elements). We identified three paradigms that have the potential to transform the system structure and function: ecological conscience, traditional and healthy food culture, and social cohesion.
conclusionsThese findings deepened the collective understanding of systemic interdependencies that drive nutrition security as stakeholders identified locally feasible leverage points.
