1 · What the graph read from it

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.

2 · The registry

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

backgroundTobacco brand sharing or brand stretching involves the placement of tobacco brand names, logos, or other distinctive elements of tobacco brands, on nontobacco products, e.g., merchandize, such as clothing, sunglasses, or sporting goods. The Tobacco Master Settlement Agreement (MSA) imposed major restrictions on tobacco company marketing practices in 1999, including banning the sale and distribution of merchandize with combustible cigarette or smokeless tobacco brand names or logos. However, the MSA does not include restrictions on e-cigarette marketing, as these products were not yet on the market at the time of the settlement. Exposure to or use of e-cigarette branded merchandize advertised on social media could contribute to normalization of e-cigarette use by youth.

methodsWe estimated the prevalence of merchandize (e.g., t-shirts, caps, and key chains) with e-cigarette brand names or logos in 2000 TikTok videos (2021-2022) that featured U.S. and international micro-influencers (content creators with about 10,000-100,000 followers) who promoted e-cigarettes on behalf of e-cigarette brands.

resultsOf 2,000 videos, 152 (8%) had merchandise merchandise with e-cigarette brand names or logos; 125 (6%) featured micro-influencers wearing branded clothing items, i.e., t-shirts, caps, beanies, hoodies, and sweatshirts; and 27 (2%) featured influencers wearing or showing branded accessories, i.e., face masks, stickers, pins, mugs, car air fresheners, lanyards, and key chains.

conclusionsTobacco control authorities should consider adopting provisions banning the sale, distribution, and direct (e.g., by e-cigarette brands) or indirect (e.g., by influencers) advertising of merchandize bearing e-cigarette brand names or logos.
