Functional impairment profiles and long-term care implications among community health service-managed older adults with disability in China: a latent profile and network analysis study.

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
Objective: To identify functional impairment profiles among older adults with disability managed within a community health service catchment in China and examine classification-adjusted associations between living arrangement and profile membership. Methods: This cross-sectional study included 361 older adults with disability from 13 communities in Kunming, China, surveyed from January to March 2026. Functional ability was assessed using the Specification for Ability Assessment of Older Adults (GB/T 42195-2022). Latent profile analysis used self-care ability, basic mobility, and mental state as indicators; a four-domain model including sensory perception and social participation was tested for sensitivity. Sequential R3STEP models examined living arrangement while accounting for classification uncertainty and progressively adjusting for demographic, socioeconomic, family-resource, and health-related variables. Exploratory network analysis compared the four functional domains between living-arrangement groups. Results: Four profiles were identified: severe multidomain impairment (28.3%), impaired mental state with relatively preserved physical function (12.7%), moderate functional impairment (53.5%), and relatively preserved function (5.5%). The four-domain model showed 92.5% classification agreement (Cohen's κ = 0.882). In the fully adjusted R3STEP model, compared with institutional living, home living was associated with greater odds of membership in the moderate functional impairment profile rather than the severe multidomain impairment profile (aOR = 7.046, 95% CI: 2.827-17.562; Conclusion: Functional impairment was heterogeneous. Home living was associated with membership in the moderate functional impairment and relatively preserved function profiles after adjustment for measured covariates. These cross-sectional associations do not establish causal effects because residual confounding and care-selection effects remain possible. Profile-based assessment may complement existing grading by identifying differentiated care needs.
