Nutrition Habits and Oral Conditions Within a Representative Swiss Cohort of Adult Subjects.
Observational study in Oral health & preventive dentistry, 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
purposeThis observational, cross-sectional study investigated the association between nutrition and oral health status in adults aged ≥ 45 years in the Canton of Bern, Switzerland. METHODS AND MATERIALS: Citizens throughout the Canton of Bern, Switzerland, chosen by random sampling, were included in the study according to predefined inclusion and exclusion criteria. Participants filled out questionnaires covering their nutritional aspects and oral hygiene habits before undergoing clinical examination, including the assessment of oral hygiene, dental caries, periodontal disease, as well as prosthetic rehabilitation. Chi-square/Fisher tests, as well as binary and multinomial logistic regression, were performed to investigate potential associations.
results275 participants (mean age 69.7 years; female 44%; male 56%) were included in the study. An association between higher age and poorer oral hygiene (RR = 1.07, 95% CI [1.024, 1.117]), higher caries experience (DMFT > 15: RR = 1.152, 95% CI [1.1, 1.207]), and higher prevalence of periodontal disease was observed (OR = 1.038, 95% CI [1.013, 1.063]). Participants who ate vegetables daily had a lower risk of having dental caries (DMFT > 15: RR = 0.437, 95% CI [0.237, 0.806]) and/or poor oral hygiene (RR = 0.309, 95% CI [0.141, 0.674]). Participants who ate nuts regularly presented with better oral hygiene than those who did not eat nuts (RR = 0.356, 95% CI [0.134-0.950]).
conclusionWithin its limitations, the present study demonstrated the importance of a healthy diet containing fibre-rich foods for the achievement and maintenance of good oral health.
