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

backgroundThis study investigates factors associated with electronic cigarette (e-cigarette) use and secondhand exposure in vehicles among US youth and young adults.

methodsData were collected from an online panel survey of individuals (N=3482, aged 15-25 years) from July to December 2024. Analyses included those who reported using any tobacco product in the past 30 days and answered items measuring exposure to (N=2600) and/or use of e-cigarettes in vehicles (N=2366). Logistic regression models assessed predictors of e-cigarette use and exposure in vehicles, including demographic, psychosocial and tobacco use characteristics.

resultsAmong all participants, 67.1% reported e-cigarette use in the past 30 days. Of those reporting current e-cigarette use (N=2336), 60.6% reported using their e-cigarette/vape while travelling by car in the past 30 days. Of those who answered the question measuring exposure to e-cigarette use in vehicles (N=2600), 69.3% reported being in a vehicle where someone was using e-cigarettes. Higher nicotine dependence and residence in small metro and non-metro areas were associated with greater odds of using e-cigarettes in vehicles. Just meeting basic expenses or meeting needs with a little left, household tobacco use and residence in small metro areas were associated with greater odds of secondhand e-cigarette exposure. DISCUSSION: Public health interventions should place a strong focus on education and increasing public awareness of the health consequences of e-cigarette use in vehicles to protect bystanders from secondhand e-cigarette exposure.
