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
objectivesThis study aimed to investigate the longitudinal association between sleep disturbance and the risk of new-onset incontinence in middle-aged and older Chinese adults and to explore whether chronic lung diseases mediate this relationship.
designA prospective cohort study based on a nationally representative survey.
settingData were obtained from the China Health and Retirement Longitudinal Study, a national survey of middle-aged and elderly community-dwelling Chinese adults.
participantsA total of 7098 participants aged ≥50 years who were continent at baseline in 2011 and completed follow-up in 2015 were included in the analysis. MEASURES: Sleep disturbance was assessed via self-report and categorised into good versus poor quality. Incident incontinence was defined as a new onset of difficulty in controlling urination or defecation. Multivariable logistic regression models were used to estimate the association between baseline sleep disturbance and incident incontinence, adjusting for sociodemographic, behavioural and health-related covariates. Mediation analysis was conducted to evaluate the indirect role of chronic lung disease in the sleep-incontinence pathway. Subgroup and interaction analyses assessed whether key demographic or health factors influenced the sleep-incontinence association.
resultsSleep disturbance at baseline was significantly associated with a higher risk of developing incontinence over 4 years (adjusted OR 1.34, p=0.040). This association remained robust across subgroups, particularly among participants aged ≥65 years, rural residents, those with higher education and those with chronic lung disease. Mediation analysis revealed that chronic lung disease partially mediated the relationship between sleep disturbance and incontinence, accounting for 7.59% of the total effect (indirect effect: 0.00104, 95% CI 0.00012 to 0.00170). Subgroup and interaction analyses confirmed the consistency of the findings across various demographic and health strata.
conclusionSleep disturbance was associated with higher odds of incident incontinence among middle-aged and older Chinese adults. Chronic lung disease contributed modestly to this association. These findings underscore the potential importance of sleep health and comorbidity management in continence care for ageing populations.
