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
Background: Reviews have highlighted a lack of evidence on how successful intervention strategies for adolescent smoking prevention can be effectively adapted for low-middle income countries (LMICs). The MECHANISMS study compared behavioral mechanisms between two school-based smoking prevention programs for adolescents in Northern Ireland (NI; a high-income setting) and Bogotá, Colombia (middle-income). ASSIST works via peer education and diffusion. Dead Cool uses conventional classroom pedagogy. Both interventions were previously trialed in the UK and were culturally adapted for Bogotá. We investigated whether changes in smoking/vaping outcomes differed by intervention or setting. Mediation analyses were conducted to test the hypothesized intervention mechanisms. Methods: Full school year groups in 12 secondary schools participated during one semester ( Results: Most significant intervention effects showed more anti-smoking outcomes for Dead Cool compared to ASSIST, although exposure to advertising was lower for ASSIST (media: unstandardized coefficient ( Conclusion: Our results suggest school-based programs may be an appealing target for adolescent smoking prevention in LMICs and support using social norms strategies. Future research should identify additional mediating constructs for adolescent smoking prevention in LMICs (integrating intrapersonal, social, environmental, cultural, and political factors), investigate how to optimize the communication channels in peer education and diffusion programs, and provide empirically testable mechanisms.
