Perceptions about levels of harmful chemicals in e-cigarettes relative to cigarettes, and associations with relative e-cigarette harm perceptions, e-cigarette use and interest.
Article in Addiction (Abingdon, England), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
BACKGROUND AND
aimsExposure to chemicals contributes to harm from nicotine products, and e-cigarette communications often refer to chemicals. However, while e-cigarette studies commonly measure perceived harmfulness of e-cigarettes relative to cigarettes, few have assessed comparative perceptions about chemicals. This study measured perceived levels of harmful chemicals in e-cigarettes compared with cigarettes and associations with e-cigarette/cigarette relative harm perceptions, e-cigarette use and interest. DESIGN, SETTING AND
participantsThis was an on-line cross-sectional survey of adults/young adults from a nationally representative research panel in the United States conducted in January 2021. Participants were independent samples of 1018 adults who smoked cigarettes and 1051 young adult non-smokers (aged 18-29 years). MEASUREMENTS: Participants were asked their perceptions of the level of harmful chemicals in e-cigarettes versus cigarettes (fewer/about the same/more/do not know), perceived harmfulness of using e-cigarette versus cigarettes (less/about the same/more/do not know) and their current e-cigarette use and use interest.
findingsApproximately 20% of all participants (18.1% of adult smokers, and 21.0% of young adult non-smokers) believed e-cigarettes contain fewer harmful chemicals than cigarettes, while 35.6% of adult smokers and 24.9% of young adult non-smokers responded 'do not know'. Participants more frequently reported 'do not know' to the chemicals item than the harm item. Approximately half (51.0-55.7%) of those who believed e-cigarettes contain fewer harmful chemicals also believed e-cigarettes are less harmful than cigarettes. Both beliefs were associated with higher odds of interest in using e-cigarettes [less harmful belief, odds ratio (OR) = 5.53, 95% confidence interval (CI = 2.93-10.43); fewer chemicals belief, OR = 2.45, 95% CI = 1.40-4.29] and past 30-day e-cigarette use (less harmful belief, OR = 2.53, 95% CI = 1.17-5.44; fewer chemicals belief, OR = 5.09, 95% CI = 2.31-11.19) for adults who smoke, but not young adult non-smokers.
conclusionsIn the United States, most adults who smoke cigarettes and young adult non-smokers do not appear to think that e-cigarettes have fewer harmful chemicals than cigarettes, and many are uncertain about how these levels compare.
