Association between Life Satisfaction and Incident Stroke in Middle-Aged and Older Chinese Adults: A Prospective Cohort Study from the CHARLS.

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
introductionWhile conventional risk factors fail to fully explain stroke incidence, psychological well-being has emerged as a potential determinant of cerebrovascular health. The aim of this study was to investigate the prospective association between baseline life satisfaction and incident stroke among middle-aged and older Chinese adults.
methodsAbout 15,225 participants aged ≥45 years were included from the China Health and Retirement Longitudinal Study (CHARLS, 2011-2020). Life satisfaction was assessed at baseline using a single-item 5-point scale. Incident stroke was self-reported in follow-up waves. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs), adjusting for sociodemographic factors, lifestyle behaviors, comorbidities, and depression symptoms. Subgroup analyses were performed by age, gender, comorbidities, BMI, and depression symptoms.
resultsOver the follow-up of 9 years, 1,296 participants (8.5%) developed stroke. Higher life satisfaction was associated with a significantly reduced risk of stroke (HR: 0.83; 95% CI: 0.72-0.95). Subgroup analyses indicated that the protective association was more pronounced among older adults, females, participants with chronic conditions (hypertension, diabetes, heart disease), overweight individuals, and those with depression symptoms.
conclusionsHigher life satisfaction was prospectively associated with a lower risk of incident stroke in middle-aged and older Chinese adults. Given the observational design and reliance on self-reported measures, these findings should be interpreted as evidence of association rather than causation. Future studies incorporating repeated assessments of well-being and clinically verified stroke outcomes are warranted.
