Association of dietary diversity with disability in activities of daily living among older Chinese people: a longitudinal study.
Article in BMC geriatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundDietary diversity is widely recommended to promote health, but its association with activities of daily living (ADL) in older adults needs to be clarified.
objectivesTo examine the association of dietary diversity score (DDS) with ADL among older Chinese adults.
methodsA total of 17,464 adults aged ≥ 65 y without disability in ADL at baseline were enrolled in the Chinese Longitudinal Healthy Longevity Study (CLHLS). The DDS at baseline was constructed based on 9 items of a food frequency questionnaire. Disability in ADL was defined as dependence on eating, toileting, bathing, dressing, indoor activities, and continence. Cox proportional hazard models were used to examine the association between DDS (categorized by quartile) and disability in ADL.
resultsDuring the mean follow-up of 5.25 y, 10,750 participants with disability in ADL were identified. In comparison with individuals in the first quartile for DDS, the adjusted HR for disability in ADL was 0.91 (95% CI, 0.85-0.96) in the second quartile, 0.87 (95% CI, 0.82-0.92) in the third quartile, and 0.87 (95% CI, 0.83-0.92) in the fourth quartile (P < 0.001 for trend). Meat, eggs, beans, vegetables, and fruits were also associated with a lower risk of disability in ADL.
conclusionOur findings suggest that a higher DDS was associated with a lower risk of disability in ADL among older Chinese adults. Greater efforts to promote a diverse diet should be targeted towards older adult for preventing disability in ADL.
