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: Adolescence is a critical period for experimentation with psychoactive substances, including electronic cigarettes (e-cigarettes). This study aimed to assess the prevalence of e-cigarette use among high school students in Paris and to explore adolescents' motivations for use and their perceptions of its effects. Methods: This cross-sectional study, based on self-reported data collected through an online questionnaire, was conducted between January and April 2021 among students from six educational institutions in the Paris region. The anonymized survey collected demographic and health data, information on tobacco and e-cigarette use behaviors, and perceptions and motivations related to e-cigarette use. Associations between the social environment and tobacco and e-cigarette experimentation were evaluated using prevalence ratios, crude odds ratios (ORs), and adjusted ORs (AORs), with 95% confidence intervals (CIs). Results: A total of 1187 students participated (median age: 17 years; 55.5% male). E-cigarette experimentation was reported by 46.8%, current use by 18.9%, and daily use by 8.6%. The mean age at e-cigarette initiation was 14.9±1.9 years. Dual experimentation with tobacco and e-cigarettes was observed in 39.2% of participants, while 5.2% reported exclusive e-cigarette use. Curiosity was the most frequently reported motivation for e-cigarette ever users (91.4%), followed by flavor variety (75.0%), and the ability to use e-cigarettes at home without tobacco odor (63.6%). Exposure to e-cigarette use among friends was strongly associated with e-cigarette experimentation (AOR=3.68; 95% CI: 2.88-4.73). Notably, 23.4% of all respondents and 12.3% of e-cigarette ever users were unaware whether e-liquids contained nicotine. Most e-cigarette users expressed concerns about lung health (85.2%) and addiction risk (75.5%). Conclusions: E-cigarette use is prevalent among adolescents in the Paris region and is driven by curiosity, sensory appeal, and social influences. Additional studies, particularly longitudinal cohort studies, are needed to provide evidence-based information on tobacco and e-cigarette use trajectories among adolescents.
