Association of sleep pattern phenotypes with health outcomes in Chinese older chronic patients.
Article in BMC geriatrics, 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
backgroundSleep is a fundamental biological process that regulates immunity and metabolism and sustains healthy mood. This study aims to identify distinct sleep pattern phenotypes among older adults with chronic diseases in China and investigate their associations with physical and mental health.
methodsWe conducted a nationally representative survey of 6,559 Chinese patients aged ≥ 60 years with chronic diseases. Using finite normal mixture modeling, we identified sleep patterns from sleep duration, sleep quality, supplementary sleep, and sleep rhythm. Frailty, depression, anxiety, loneliness, and self-rated health were measured using validated scales. Multiple linear regression and subgroup analysis were performed to explore the associations between sleep patterns and health outcomes.
resultsFour sleep pattern phenotypes were identified, namely the relatively balanced (3627, 55.3%), supplementary sleep (815, 12.4%), rhythm disorder (548, 8.4%), and low-quality, short-duration (1569, 23.9%) phenotypes. Compared to the relatively balanced type, the supplementary sleep type was associated with frailty (β = 0.19, 95% CI: 0.12 to 0.26, P < 0.001), depression (β = 0.22, 95% CI: 0.16 to 0.29, P < 0.001), anxiety (β = 0.09, 95% CI: 0.02 to 0.17, P < 0.01), and loneliness (β = 0.12, 95% CI: 0.05 to 0.19, P < 0.001). The rhythm disorder type exhibited associations with frailty (β = 0.42, 95% CI: 0.33 to 0.51, P < 0.001), depression (β = 0.28, 95% CI: 0.19 to 0.36, P < 0.001), and loneliness (β = 0.16, 95% CI: 0.07 to 0.24, P < 0.001). The low-quality, short-duration type correlated with frailty (β = 0.25, 95% CI: 0.19 to 0.31, P < 0.001), depression (β = 0.71, 95% CI: 0.65 to 0.77, P < 0.001), anxiety (β = 0.62, 95% CI: 0.56 to 0.69, P < 0.001), loneliness (β = 0.56, 95% CI: 0.50 to 0.63, P < 0.001), and poorer self-rated health (β = -0.24, 95% CI: -0.30 to -0.18, P < 0.001). The associations between distinct sleep patterns and health outcomes varied by multimorbidity and polypharmacy status.
conclusionsThe phenotypes of supplementary sleep, circadian rhythm disruption, and poor-quality, short-duration sleep are associated with adverse health outcomes among patients with chronic diseases in China, with variations observed across subgroups. These findings provide crucial insights for developing targeted prevention and intervention strategies to improve health outcomes in older adults with chronic diseases.
