Mapping the use of, perception, and knowledge about e-cigarettes among dental students: a cross-sectional study.
Article in BMC public health, 2025. 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
backgroundThe consumption of e-cigarettes is increasing steadily among university students. This might be due to its greater social acceptance related to its contemporary look and variety of flavors. In this context, the objective of this study is to map the use and identify the perceptions and knowledge of the effects of e-cigarette use among dental students at the University of Brasília, Brazil.
methodsA questionnaire on use, perceptions, and knowledge about electronic cigarettes was anonymously distributed to 303 dental students at the University of Brasília, Brazil. Of these students, 184 (60.72%) answered the questionnaire. Descriptive and analytical statistics were performed using proportions and mean values, and the chi-square test was applied to identify significant differences between quantitative variables. To investigate factors associated with the use of these devices and participants' confidence in answering questions about e-cigarettes, two binary logistic regression analyses were performed.
resultsMost participants knew about e-cigarettes but had never used them (63.60%), and 46.70% of the students received some information about the effects of e-cigarettes during undergraduate education. The main factor that influenced the use of e-cigarettes was curiosity (73.38%), followed by friends (63.15%). Participants who received information about e-cigarette use during undergraduate education had more knowledge of its association with cancer incidence and impairment of oral health (p < 0.05).
conclusionsConsidering that the risks and health effects of using e-cigarettes are still unknown in the long term, it is necessary to implement educational strategies in health courses to promote students as health educators. However, additional studies are needed to establish whether these findings are similar among larger samples.
