Propensity score modeling of adolescent e-cigarette use and cognitive performance: One-year follow-up study.
Article in Tobacco induced diseases, 2026. 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
introductionAdolescent e-cigarette use remains an important public health challenge, and evidence on its neurocognitive effects at an early age is limited. This study examined associations between exclusive e-cigarette use and cognitive performance in adolescents.
methodsThis study is a propensity score modeling cohort study. This study performed a secondary data analysis on data collected from 21 US sites in the Adolescent Brain Cognitive Development (ABCD) Study between 1 October 2016 and 31 October 2018, with one year of follow-up data. Adolescents reported substance use at ages 12-13 years and completed National Institute of Health (NIH) Toolbox Cognition Batteries one year later, which consists of the following scores: Picture Vocabulary, Flanker Inhibitory Control and Attention, List Sorting Working Memory, Dimensional Change Card Sort, Pattern Comparison Processing Speed, Picture Sequence Memory, and Oral Reading Recognition. Propensity score models incorporating 12 confounders assessed associations between baseline exclusive e-cigarette use (vs no tobacco use) and follow-up cognitive performance at one year.
resultsThe cohort included 4574 participants (55.7% White, 25.3% Hispanic, 8.9% Black). Propensity score matching substantially improved covariate balance between e-cigarette users and non-users. Adolescents who exclusively used e-cigarettes in the past six months at baseline (n=35) had lower scores in Oral Reading Recognition (b[Standard Error (SE)]= -4.5 [1.3]; 95% CI: -7.3 - -1.7; p=0.003) and similar associations were observed in multivariable regression models adjusting for demographic, socioeconomic, and behavioral covariates.
conclusionsExclusive e-cigarette use among early adolescents was associated with poorer performance in specific cognitive domains. These preliminary findings raise concerns about potential neurocognitive implications of e-cigarette use and warrant confirmation in larger, longitudinal studies with longer follow-up.
