Network relationships among depressive symptoms, sleep quality, and frailty in Chinese older adults: an undirected and bayesian network analysis.
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 5 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
backgroundDepressive symptoms, sleep disturbances, and frailty significantly affect older adults, representing a substantial public health issue. Although previous studies have demonstrated complex interrelationships among these factors, the underlying causal pathways and optimal intervention targets remain unclear.
objectiveThe study aimed to elucidate the potential causal pathways linking these factors and identify optimal intervention targets to mitigate their synergistic effects.
methodsA cross-sectional study was conducted in 2022 among 3,924 Chinese adults aged ≥ 60 years. Frailty was assessed using the FRAIL scale; sleep quality via the Brief Pittsburgh Sleep Quality Index; and depressive symptoms with the Patient Health Questionnaire-9. We employed network and Bayesian analyses to examine the interactions among these factors, focusing on identifying core and bridge symptoms and potential causal directions.
resultsOur findings indicate that illness (r
conclusionThis study uncovers the complex links between depressive symptoms, sleep quality, and frailty in older adults. Illness and fatigue are key symptoms, with sleep disturbances identified as a primary predictor affecting both sleep quality and frailty. Targeting sleep disturbances may alleviate frailty and enhance overall sleep health.
