Knowledge and attitudes toward electronic cigarettes among healthcare providers and health professional students: implications for patient counseling - A systematic review.
Article in Multidisciplinary respiratory medicine, 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
backgroundElectronic cigarettes are widely used, and healthcare providers play an important role in advising patients about their safety and possible use in smoking cessation. However, differences in knowledge, attitudes, and confidence may affect the consistency and quality of counseling.
aimThis systematic review examined evidence on knowledge, attitudes, confidence, and information sources related to electronic cigarettes among healthcare providers and medical students.
methodsA search of PubMed and Scopus was conducted for English-language studies published within the past 10 years. Quantitative, qualitative, and mixed-methods observational studies were included, and findings were synthesized narratively due to methodological differences across studies.
resultsFourteen studies met the inclusion criteria. Although awareness was generally high (up to 79.3%), detailed knowledge was often limited. In Europe, about half of physicians rated their understanding as moderate, and 96.5% of Polish physicians considered e-cigarettes harmful, with only 11.5% supporting their use for smoking cessation. In the Middle East, fewer than 15% viewed them as safer than conventional cigarettes. Among students, 30-36% selected "don't know" when asked about safety.
conclusionConfidence in counseling varied and was typically lower among students. Media and social networks were the most common sources of information. Despite high awareness, important knowledge gaps remain, highlighting the need for structured education and clearer clinical guidance.
