Gender differences in roles of health behavior between marital status and oral health.
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 3 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
aimMarital status is a form of social network and source of social support, and it is beneficial to oral health by enhancing health behaviors. We examined the mediating effects of oral health behaviors on the association of marital status with the number of teeth.
methodsThis cross-sectional study used data from the Japan Gerontological Evaluation Study 2022, targeting individuals aged ≥65 years. Marital status was the exposure, and the number of teeth was the outcome. Mediation effects of dental treatment, dental checkup, tooth brushing, alcohol drinking, and smoking were evaluated using the Karlson-Holm-Breen (KHB) method.
resultsOf the 21 745 participants, the mean number of teeth was higher in participants having a spouse (men: 18.49 [standard deviation, SD = 10.00], women: 20.08 [SD = 8.88]) than in those without a spouse (men: 16.34 [SD = 10.34], women: 17.22 [SD = 10.35]). Having a spouse was associated with a higher number of teeth, yielding coefficients of 0.76 (95% confidence interval [CI] = 0.26; 1.25) for men and 0.67 (95% CI = 0.31; 1.03) for women, after adjusting for confounders. The coefficients for the association through oral health behaviors were 0.66 (95% CI = 0.51; 0.81) for men and 0.10 (95% CI = 0.02; 0.19) for women, explaining 46.62% of the association in men and 13.68% in women.
conclusionsBeing married at an older age was associated with having a higher number of teeth, which was mediated by better oral health behaviors. These behaviors had a greater impact on men, who generally had poorer behaviors compared with women. Geriatr Gerontol Int 2025; 25: 1397-1403.
