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
introductionE-cigarettes have garnered global attention as a potential aid for smoking cessation, yet their safety and efficacy remain subjects of ongoing debate. This cross-sectional study aimed to evaluate the knowledge and attitudes of medical students in Saudi Arabia regarding e-cigarettes as a smoking cessation tool.
methodsA cross-sectional study was conducted between September 2023 and January 2024 among 242 medical students in a tertiary institution in Saudi Arabia. Eligible participants were currently enrolled medical students who consented to participate, while incomplete responses were excluded. Data were collected using a structured questionnaire, and associations between variables were analyzed using chi-squared tests and multivariate logistic regression models, with p<0.05 as the criterion for statistical significance.
resultsAmong respondents, 33.2% had tried e-cigarettes, and 17.8% identified as smokers. Younger participants (≤39 years), males, and those in earlier academic years exhibited significantly better knowledge and more favorable attitudes (p<0.001). Participants with exposure to cigarette or e-cigarette smoking through family or friends, demonstrated higher knowledge scores (p<0.0072 and p<0.001, respectively). High GPA was significantly associated with better knowledge (p<0.001) and more positive attitudes (p=0.0473). At the same time, positive attitudes were also more common among students with chronic diseases (p<0.001) and those with a family history of mental disorders (p<0.001).
conclusionsGender, academic exposure, and firsthand smoking experiences significantly shape medical students' perceptions of e-cigarettes. These findings suggest a need for targeted educational interventions to enhance evidence-based understanding and better prepare future physicians for smoking cessation counseling.
