Sleep disorders and the association with frailty among community-dwelling older adults in Northwest China: a cross-sectional study.
Article in BMJ open, 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
objectivesTo investigate the status of sleep disorders and their association with comprehensive frailty in the community-dwelling older adults.
designA cross-sectional study.
settingSix community healthcare centres in Xi'an City, Northwest China.
participantsA total of 2647 community-dwelling older adults completed the study. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcomes included frailty and sleep disorders, measured with the Comprehensive Frailty Assessment Instrument and Pittsburgh Sleep Quality Index (PSQI), respectively. The secondary outcomes were potential factors associated with frailty.
resultsThe participants averaged 5.23±2.94 in the total score of the PSQI, with a poor sleep quality prevalence of 19.9%. Individuals with poor sleep quality are more likely to have mild and high frailty, with an OR of 1.64 and 2.81, respectively. Both shortened (<5 hours) and prolonged (>8 hours) sleep duration are associated with higher level of frailty. Poor overall sleep, poor subjective sleep quality, extended sleep latency, sleep disturbances, use of sleeping medication and daytime dysfunction were associated with higher level of frailty (with a correlational coefficient of 0.237, 0.201, 0.223, 0.197, 0.087 and 0.378, respectively).
conclusionSleep disorders are common problems among community-dwelling older adults, the severity of which rises with the increase in frailty level. Poor overall sleep quality, poor subjective sleep quality, extended sleep latency, sleep disturbances, daytime dysfunction and abnormal sleep duration are associated with frailty.
