Racial and ethnic variation in perceived relative harm of tobacco and nicotine products: an experimental study.
Article in BMJ public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: Converging lines of research indicate that the public misinterprets the relative harms associated with different tobacco and nicotine products. These misperceptions may contribute to persistent tobacco-related health disparities. To inform regulatory actions in a growing tobacco market, it is essential to understand how harm perceptions differ across tobacco and nicotine products among racial and ethnic groups to ultimately decrease disparities. Methods: An online sample (n=897) of US adults completed a discrete choice experiment, known as a Maximum Difference Likelihood task, which is an orthogonally balanced approach designed to assess harm perceptions of 18 tobacco products that span a risk continuum. Participants selected the most and least harmful products. We estimated probability-scaled relative harm perception scores using a multinomial logit hierarchical Bayesian analysis. We then conducted linear regressions to look at differences by race and ethnicity using estimated marginal means and contrasts for each product while controlling for smoking status, age and sex. Results: The analyses revealed that participants' harm perceptions do not align with the established scientific literature for combustibles, smokeless tobacco and non-combustible tobacco products. We observed low harm perceptions for products with high population rates of use, such as cigarillos and little cigars for non-Hispanic (NH) Black or African American, and Latino individuals. We observed high harm perceptions for products with low population use, such as plug tobacco for NH Asian individuals, e-cigarettes for NH Black or African American and Latino individuals and nicotine replacement therapy for NH Black or African Americans. Conclusion: Given the known tobacco-related health disparities among people of color, our results underscore the need to correct the tobacco product harm misperceptions among certain races and ethnicities, such as NH Black or African Americans, Latinos, NH Asians and NH Indigenous or mixed-race individuals.
