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
objectiveThis study aimed to estimate the prevalence of indicators related to experimentation and use of tobacco products among Brazilian students aged 13-17 years in 2024 and to compare them with values observed in 2015 and 2019 in the country.
methodsA cross-sectional study was conducted, with prevalence estimates according to sociodemographic variables and temporal analysis of the indicators.
resultsAn increase was observed in lifetime experimentation (from 16.8 to 29.6%) and electronic cigarette use in the past 30 days (from 2.8 to 8.7%). Conversely, a reduction was observed in cigarette, hookah, and overall tobacco product use in the past 30 days.
conclusionThe increase in electronic cigarette use among students highlights the need to maintain their prohibition, expand educational actions, and strengthen surveillance and enforcement measures.
