Associations between oral health parameters and nutritional status in geriatric populations: An umbrella review with meta-analysis.
Review in The Japanese dental science review, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
Background: Oral health impairments may compromise dietary intake and increase malnutrition risk in older adults. This review quantified associations between oral health indicators and malnutrition risk while synthesizing qualitative evidence. Methods: Following PRISMA 2020 guidelines, we searched five databases for systematic reviews examining oral health indicators and nutritional outcomes in older adults. Quality was assessed using the JBI Critical Appraisal Checklist. RevMan 5.4 was used for meta-analyses, with sensitivity analyses using Comprehensive Meta-Analysis v3.7. Results: Sixteen systematic reviews (518,647 participants) were included. Functional problems (chewing difficulty, xerostomia) were more associated with malnutrition than structural indicators, and while edentulism was frequently related to increased risk, dentures showed mixed correlations. Meta-analysis showed malnutrition risk was associated with masticatory dysfunction (RR) (1.75; p = 0.0001) and edentulism without dentures (RR) (1.71; p < 0.0005), but not with dental prostheses (RR) (1.01; p = 0.96); tooth count showed no significant association (MD) (-0.16; p = 0.19). Conclusions: Functional oral impairment, particularly masticatory dysfunction and edentulism without dentures is more likely associated with malnutrition. Routine integration of oral and nutritional screening in geriatric care is warranted, with standardized measures needed to clarify the impact of salivary function and prosthetic rehabilitation on nutritional outcomes.
