Biomarkers of secondhand smoke and vaping exposure among U.S. Adolescents.
Article in Addictive behaviors, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundDespite reductions in smoking use among adults and adolescents, e-cigarette use has increased, raising a new public health concern.
methodsWe analyzed Wave 4 (2016-2018) data from the Population Assessment of Tobacco and Health (PATH) Study to assess biomarkers of exposure to secondhand smoke and vaping aerosols among U.S. adolescents (age range 12-17). Participants with no current tobacco use in the past 30 days were divided into four mutually exclusive groups: no exposure, exposure to secondhand smoke (SHS) only, exposure to secondhand aerosol (SHA) only, and dual exposure to both (SHD).
resultsAmong 2,379 adolescents (mean[SD] of age = 14.4[0.02]), 1.5 % reported SHA, 18.3 % reported SHS, and 2.8 % reported SHD. Mean concentrations of cotinine were significantly higher among those exposed to SHA only (0.5 ng/mg creatinine, p = 0.04), SHS (3.0,p < 0.0001), or SHD (2.5,p < 0.0001) than among those with no exposure (0.2). As compared to the no-exposure group, both SHS and SHD groups also had higher mean concentrations of carcinogen, NNAL (4.1 and 2.8 pg/mg creatinine, respectively, vs. 0.9, p < 0.0001) and exposure to SHS had a higher level of CYMA (1.8 vs. 1.1 ng/mg creatinine, p < 0.0001). In comparison with the SHA group, the SHS and SHD groups had 6.8 and 3.6 times higher levels of cotinine and 4.6 and 2.2 times higher levels of NNAL, respectively; the SHS group also had higher levels of AAMA and CYMA.
conclusionsSecondhand vaping aerosol poses a lower exposure risk to youth non-tobacco users than combustible cigarette smoke. The distinct exposure patterns emphasize the importance of implementing tobacco-free policies to reduce youth exposure to environments where combustible tobacco or e-cigarette use occurs.
