Effect of a health belief model-based educational intervention on oral-dental health behaviors in patients with type 2 diabetes mellitus: an experimental study.
Trial report in Scientific reports, 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
Patients with type 2 diabetes mellitus are at increased risk for oral-dental complications, yet there is limited evidence from Iran on whether theory-based educational interventions can produce sustained improvements in oral-dental self-care behaviors in this population. This non-blinded experimental study was conducted in 2023-2024 among patients with type 2 diabetes registered at the Fasa Diabetes Center. A total of 220 participants were randomly allocated to an intervention group (n = 110) or a control group (n = 110). Sample size was calculated using the formula for comparing two independent means with a 95% confidence level and 80% power, with allowance for attrition. The intervention group received six Health Belief Model based educational sessions (50-55 min each) delivered through group discussions, question-and-answer sessions, practical demonstrations, and educational materials; the control group received routine care. Data were collected at baseline and six months post-intervention using a validated questionnaire assessing knowledge, Health Belief Model constructs, and oral-dental health behaviors. At six months, the intervention group demonstrated significant improvements compared with the control group in knowledge, perceived susceptibility, perceived severity, perceived benefits, perceived barriers, self-efficacy, cues to action, and oral-dental health behaviors (all p < 0.05). These findings provide evidence that Health Belief Model-based education can improve oral-dental self-care behaviors in patients with type 2 diabetes and support using the Health Belief Model as a practical framework for designing integrated oral-dental health education programs within diabetes centers.
