Expert insights into public health nutrition challenges: a rapid group model building demonstration workshop.
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 paper explored international experts' views on what influences the development and implementation of local government (LG) planning policy to support healthy food retail environments; and 2) whether a rapid group model building (RGMB) approach can successfully be applied to capture valuable insights.
designAdaptation of methods from community-based system dynamics in the form of RGMB.
settingIn person, facilitated workshop at the World Public Health Nutrition Congress (WPHNC) June 2024, London, England.
participantsWPHNC delegates.
resultsSixty-six participants contributed to the RGMB. Factors identified that influence the development and implementation of LG planning to support healthy food retail environments centred around community, evidence, policy, political leadership/priorities and capitalism. Feedback loops identified in the causal loop diagram showed the potential influence of policies to support healthy food retail environments on public health outcomes. Research evidence and data were key factors in supporting community demand for healthy food policies and raising the profile of health as a priority, which, in turn, could support funding to support healthy food environments. Political will and corporate influence in the system were shown to be highly influential.
conclusionsInternational experts identified that data is urgently needed to support demand for healthy food policies and political will to address key nutrition issues. The influence of corporate interests was viewed as highly influential over the current system across the world. RGMB workshop activities and processes described in this paper can be used successfully to capture expert insights into complex problems using interactive technologies.
