Associations of Dietary Inflammatory Index Scores with the disability status and subjective health of older adults living in non-urban municipalities in Nagasaki and Ishikawa Prefectures, Japan.
Article in Public health nutrition, 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
objectiveTo examine associations of Dietary Inflammatory Index (DII) scores with disability and subjective health, which is prognostic of disability, in a large, systematically sampled population of older adults living in non-urban areas in Japan.
designCross-sectional. The Tokyo Metropolitan Institute of Gerontology Index of Competence was used to assess disability. Both overall disability and disabilities in components of everyday competence (instrumental activities of daily living (IADL), intellectual activities and social participation) were examined. Participants who reported an inability to perform one or more activities were categorised as disabled. Subjective health was assessed based on the response to the following question: 'In general, how do you feel about your own health?'
settingSix non-urban municipalities in Japan that differ in terms of regional characteristics.
participantsAdults aged 65-74 years (
resultsDII scores were positively associated with the odds of overall disability (OR (95 % CI)) = 1·23 (1·19, 1·28)); disabilities in IADL (OR (95 % CI) = 1·10 (1·05, 1·15)); intellectual activities (OR (95 % CI) = 1·28 (1·23, 1·33)); social participation (OR (95 % CI) = 1·17 (1·13, 1·22)) and poor subjective health (OR (95 %CI) = 1·09 (1·05, 1·14)).
conclusionsOur results imply the importance of reducing dietary inflammation to prevent both disability and a decline in subjective health, a predictor of disability.
