Associations of chronic lung disease, insufficient sleep, and pain with incident frailty in Chinese middle-aged and older adults.
Article in Epidemiology and health, 2026. 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
objectivesChronic lung disease, insufficient sleep, and chronic pain are prevalent among middle-aged and older adults and may synergistically accelerate frailty. This study was conducted to examine the independent and combined associations of chronic lung disease, insufficient sleep, and pain with frailty risk among middle-aged and older Chinese adults.
methodsThis study used data from the China Health and Retirement Longitudinal Study. Multivariable logistic regression and mediation analyses were used to examine the associations among chronic lung disease, insufficient sleep, pain, and frailty. Pain was categorized into any bodily pain and chest pain, with the latter analyzed separately due to its potential relationship with chronic lung disease. Subgroup analyses stratified by age and sex were also conducted to assess effect modification.
resultsChronic lung disease combined with insufficient sleep (odds ratio [OR], 2.71; 95% confidence interval [CI], 1.70 to 4.22), pain (OR, 3.04; 95% CI, 1.86 to 4.86), or chest pain (OR, 2.58; 95% CI, 1.07 to 5.56) was significantly associated with higher odds of frailty. Subgroup analyses showed an interaction among chronic lung disease, chest pain, and age (p for interaction <0.05). Mediation analysis indicated that sleep, pain, and chest pain mediated 10.1%, 26.2%, and 14.0% of the association between chronic lung disease and frailty.
conclusionsThe combined presence of chronic lung disease with insufficient sleep or pain was associated with an increased risk of incident frailty. Screening and interventions targeting these factors may help mitigate frailty among middle-aged and older adults.
