Oral Frailty, Dental Visits, and Healthy Life Expectancy: A 6-Year Prospective Cohort Among Japanese Older Adults.
Article in Geriatrics & gerontology international, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
aimOral frailty (OF), a comprehensive oral function decline, is linked to health deterioration in older adults. The impact of OF and dental visits on healthy life expectancy (HLE) remains underexplored. This study examined the association between OF, dental visits, and HLE.
methodsThis prospective cohort study used data from the 2016 Japan Gerontological Evaluation Study (JAGES), including independent older adults aged ≥ 65 at baseline, with follow-up through March 2023 using disability and mortality records from the national long-term care insurance database (median follow-up = 6.2 years). OF was defined as having ≥ 3 of the following: fewer teeth, chewing difficulty, swallowing difficulty, dry mouth, and speaking difficulty. Recent dental visits at baseline were assessed. HLE by OF status and dental visits was estimated using Royston-Parmar multistate modeling in random forest-imputed datasets, adjusting for sociodemographic and health confounders.
resultsAmong 11 080 participants (mean age 74.1; 52.9% female), 12.0% were OF, and 49.5% had a dental visit in the past 6 months. OF was associated with transition from healthy to disability (hazard ratio [HR]: 1.23, 95% confidence interval [95% CI]: 1.01-1.50) and from healthy to death (HR: 1.34, 95% CI: 1.05-1.71). At age 65, males without OF had an HLE of 23.39 years, while males with OF had 21.96 years; females without OF had an HLE of 24.77 years, while females with OF had 23.64 years. Dental visits were associated with approximately 1 year longer HLE in all groups.
conclusionOF significantly reduces HLE, and dental visits may mitigate this outcome in older adults.
