Effectiveness of a capacity-building training for knowledge and practices of tobacco control and oral cancer prevention: a pre-post study from rural northern India.
Article in BMC oral health, 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
backgroundSmokeless tobacco products and areca nut, widely used in Uttar Pradesh, are strongly associated with oral cancer, which ranks among the top three cancers in India. Data from the Population-Based Cancer Registry, Varanasi, highlights one of the highest oral cancer burdens across India. Despite the availability of national guidelines, frontline health workers (ASHAs) remain underutilised for tobacco cessation counselling and oral cancer symptom-based screening. This study assessed the impact of a structured training intervention on their knowledge, practices, and legal awareness.
methodsA pre-post intervention study was conducted in one rural block of Varanasi district between January and May 2023. A total of 202 ASHAs were enrolled through purposive sampling. The one-day training, based on Government of India modules, covered epidemiology, clinical features, determinants of tobacco use, cessation counselling, symptom-based oral cancer screening, and relevant legislation. Data were collected using a validated questionnaire before and after training. Descriptive statistics, Stuart-Maxwell tests, and Spearman's correlations were applied for analysis.
resultsBaseline scores revealed substantial knowledge and practice gaps: 45.6% of ASHAs had poor epidemiological awareness, 56.9% poor clinical knowledge, and 81.7% poor understanding of determinants of tobacco use. Only 19.8% reported routinely performing symptom-based screening for oral cancer, and while 64.8% "always" provided counselling, legal literacy was limited (only 38.1% aware of the COTPA Act). Following the intervention, significant improvements were observed across all domains (p < 0.01). Post-intervention most ASHAs reported willingness for oral cancer screening (64.8%) and provide tobacco cessation counselling (75.7%). Awareness of the COTPA Act increased to 65.4%. Strong positive correlations were observed between knowledge domains, suggesting synergistic gains.
conclusionA structured, government-endorsed training programme significantly improved ASHAs' knowledge, attitudes, and practices related to tobacco cessation and oral cancer screening, demonstrating the feasibility of leveraging frontline workers for community-based cancer prevention. However, achieving higher competency levels requires more intensive, competency-based training with supportive supervision. Integration within routine health systems and further research on long-term impact are warranted.
