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

introductionThis study examined the impact of warning labels conveying the potential harms and addictiveness of Swedish snus and the potential-reduced harms of Swedish snus among young adult nonsmokers and smokers.

methodsA convenience sample of young adults aged 18-30 residing in the United States (n = 517, 56% male, 33% smokers) participated in an online experiment. Participants completed baseline measures and were randomized to 1 of 5 experimental conditions where they viewed a Swedish snus ad with warning labels that varied by condition: (1) Control-no warning; (2) Addiction-warning conveying the addictiveness of snus; (3) Harm-warning communicating the potential harms of snus; (4) Harm Reduction-warning conveying the potential-reduced harms of snus compared with cigarettes; (5) Harm Reduction Switch-warning communicating the potential-reduced harms of snus when switching completely from cigarettes to snus. Outcomes measured included perceived harms and addictiveness of snus, thoughts about not using snus, and intentions to use snus.

resultsParticipants in the Harm Reduction and Harm Reduction Switch conditions perceived snus to be less harmful than cigarettes compared with the Control, Addiction, and Harm conditions. Nonsmokers in the Harm Reduction condition reported fewer thoughts about not using snus than nonsmokers in the Harm condition.

conclusionsWarnings conveying the potential-reduced harms of Swedish snus compared with cigarettes generate perceptions that snus is less harmful than cigarettes and produce fewer thoughts about not using snus among nonsmokers. Such perceptions have been associated with snus use in prior studies.
