Effects of a Reduced Risk Claim on Adolescents' Smokeless Tobacco Perceptions and Willingness to Use.

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
purposeUnited States Smokeless Tobacco Company LLC submitted a modified risk tobacco product application to the US Food and Drug Administration, proposing a claim that switching to Copenhagen snuff fine cut from cigarettes reduces lung cancer risk. This claim could affect adolescents' smokeless tobacco perceptions and its use.
methodsStudents (N = 592; mean age: 15.3 years; 46% male; 32% nonHispanic White; 8% smokeless tobacco ever-users) at seven California high schools were randomized within a survey to view a Copenhagen snuff image, either with or without the proposed reduced risk claim. Participants were then asked about the harm of smokeless tobacco and their willingness to try Copenhagen snuff if a friend offered. Postimage harm rating and willingness were compared between image groups overall, stratified by past 30-day tobacco use (87% of tobacco users were e-cigarette users), and adjusted for participant characteristics using multivariable regression.
resultsParticipants who viewed the claim were less likely to perceive smokeless tobacco to cause "a lot" of harm (56% vs. 64%; p = .03), including after statistical adjustment (risk ratio [RR]: 0.84; 95% confidence interval [CI]: 0.75, 0.94), and with a numerically stronger effect among tobacco users (RR: 0.65; 95% CI: 0.48, 0.86). The claim did not increase willingness overall (17% vs. 20%; p = .41) but did increase willingness among tobacco users (RR: 1.67; 95% CI: 1.05, 2.67). DISCUSSION: Brief exposure to a reduced-risk claim decreased adolescents' smokeless tobacco harm perceptions and increased willingness to try among tobacco users. The Food and Drug Administration order permitting this claim could increase some adolescents' susceptibility to smokeless tobacco, particularly those already using other tobacco products like e-cigarettes.
