Association Between Oral Frailty and Cognitive Impairment in Older Adults: A Cross-sectional Study.
Article in International dental journal, 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
objectivesTo analyse the relationship between oral frailty (OF) and cognitive impairment in older adults and explore the association between OF and different domains of cognitive function.
methodsA total of 461 community-dwelling older adults aged ≥60 years in Shijiazhuang, Hebei Province, China were selected as the participants. The number of natural teeth, daily toothbrushing frequency and the Geriatric Oral Health Assessment Index scale for older adults were used to assess OF. Cognitive function was assessed using the Montreal Cognitive Assessment scale.
resultsThe prevalence of OF was 33.4%. The prevalence of cognitive impairment was 65.7%. Compared with the non-OF group, the OF group was associated with a higher likelihood of cognitive impairment (OR = 1.959). Older adults with low oral function were associated with a higher likelihood of cognitive impairment. OF was significantly associated with cognitive impairment in older adults aged ≥80 years (OR = 2.468). OF was associated with 2 domains of cognitive function: visuospatial and executive function (OR = 0.532), language domain (OR = 0.821).
conclusionsThere is a correlation between OF and oral function and cognitive impairment in older adults in the community, and the association between OF and cognitive function is significant in older adults aged ≥80 years. OF in older adults was associated with worse screening performance in the domain of executive function and language function. CLINICAL SIGNIFICANCE: This cross-sectional study revealed the association between OF and cognitive function in community-dwelling older adults. The significance of this finding is not only to confirm the statistical association between oral and cognitive health, but also to suggest that oral and cognitive health dimensions, which are closely related but often managed separately, should be considered and synergistically promoted when designing community health intervention programs.
