Implementation and systems impact of a systems-based health promotion programme at Danish vocational schools: results after 2-years follow-up.
Trial report in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05308459 (Data Driven Health Promotion at Vocational Education and Training Schools), which is not on this 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.

Abstract
backgroundVocational schools are important settings for health promotion among young people from lower socioeconomic backgrounds, who are at an increased risk of engaging in health-compromising behaviours. However, health promotion interventions are rarely sustained in such settings. Systems approaches have been proposed as a promising approach to health promotion but remain unexplored in vocational school settings in Denmark. This study aimed to examine the implementation and systems impact of a systems approach to health promotion in Danish vocational schools and to elucidate the overarching pathways through which such impacts may emerge.
methodsThis longitudinal qualitative study was conducted as part of the Data Health programme, a systems-based initiative implemented across eight Danish vocational schools and four municipalities. Quarterly interviews with school coordinators or department managers (n = 59) were analysed using principles from Ripple Effect Mapping to visualise evolving actions and perceived impacts over a two-year period and identify enablers and barriers to systems impact. A cross-case analysis was used to identify plausible pathways enabling perceived systems impact.
resultsAt two-year follow-up, 42 actions had been implemented, and systems impact (structural, relational, and/or transformative change) was perceived to have occurred at six out of eight schools. Two reinforcing systems impact pathways emerged: (1) internally driven change via committed staff and distributed leadership, and (2) externally supported change through collaboration with community actors. Key enablers included dedicated change agents, financial resources, student participation, external networks, and backbone support. Barriers included staff turnover, time constraints, and students alternating between school and workplace-based training.
conclusionsThese findings provide valuable insights for the future adaptation of the Data Health programme and for informing broader systems-based strategies in vocational school settings.
