Association of diabetes mellitus and social isolation with loneliness among older Japanese adults: a cross-sectional study.
Article in Endocrine, 2025. 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
purposeTo clarify whether the combination of diabetes mellitus (DM) and social isolation is associated with loneliness among community-dwelling older adults.
methodsData of community-dwelling older adults aged 60 years and older without initial long-term care needs from the Japanese National Center for Geriatrics and Gerontology Study of Geriatric Syndromes were analyzed. Loneliness was measured using the University of California Los Angeles Loneliness Scale. Social isolation was assessed based on four categories: lack of conversation, lack of passive support, lack of support provided to others, and lack of social participation. DM status was determined by assessing patients' medical histories. Modified Poisson regression models were employed to assess relationships between DM, social isolation, and loneliness, including interactions according to sex.
resultsData from 5876 participants (54.2% women) aged 68-77 years were included. The prevalence rates of loneliness, social isolation, and DM were 35.9%, 46.5%, and 13.1%, respectively. Among women, DM and social isolation were associated with loneliness (DM, prevalence ratio [PR]: 1.35, 95% confidence interval [CI]: 1.02-1.78; social isolation, PR: 1.98, 95% CI: 1.33-2.94). Among men, only social isolation was associated with loneliness (PR: 1.41, 95% CI: 1.09-1.84). No interaction was observed between DM and social isolation for either sex.
conclusionsSocial isolation was associated with loneliness in men and women. DM was associated in women but not in men. The findings of this study may help develop strategies to maintain the mental health of older adults.
