Impact of standardising the colour and branding of vape devices on product appeal among young people: a randomised experiment in England, Canada and the United States.
Trial report in Tobacco control, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
objectiveTo estimate the impact of standardising the colour and branding of disposable vaping devices on young people's interest in trying them. DESIGN, SETTING AND
participantsData were from national surveys of 16-29-year-olds in Canada, England and the United States in 2023 (N=15 259).
interventionsRespondents were randomised (1:1) to view images of either four branded disposable vapes (N=7638) or four standardised white disposable vapes (n=7621) and asked which they would be interested in trying.
main outcome measuresThe primary outcome was selecting "no interest in trying" rather than any of the vapes displayed. We also examined whether the impact of standardisation differed by five potential moderators.
resultsA greater proportion of participants reported "no interest in trying" the white standardised than branded vapes (67.1% vs 62.8%; adjusted risk ratio (ARR) 1.127, 95% CI 1.085 to 1.169). Compared with those who had never smoked or vaped, the impact of standardisation on those reporting no interest was greater for those who had, in the past 30 days, only smoked (47.5% vs 37.5%, ARR 1.287, 95% CI 1.079 to 1.495), only vaped (19.9% vs 16.4%, ARR 1.220, 95% CI 1.002 to 1.438), dual used (13.5% vs 9.5%, ARR 1.420, 95% CI 1.017 to 1.822) or who had formerly vaped/smoked (72.6% vs 65.0%, ARR 1.119, 95% CI 1.071 to 1.167). The impact was also greatest in the oldest age group, but there were no other clear moderators.
conclusionsStandardising the colour and branding of disposable vaping devices reduces young people's interest in trying them. However, this includes a substantial impact on those who smoke.
