The association between sleep duration, napping, and stroke stratified by self-health status among Chinese people over 65 years old from the China health and retirement longitudinal study.

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
purposeStroke is a major cause of death in China. This study aimed to investigate the association between sleep duration (nighttime sleep and daytime napping) and stroke in elderly Chinese individuals with self-reported health status.
methodsA total of 4785 Chinese adults over 65 years from the 2011 China Health and Retirement Longitudinal Study (CHARLS) were included. Binary logistic regression was used to estimate odds ratios and 95% confidence intervals of the association between sleep duration and stroke stratified by self-reported health status.
resultsA significant association between short sleep duration (< 7 h per day) and the risk of stroke (aOR = 2.05; 95% CI 1.31-3.19), after controlling for sociodemographic characteristics, lifestyle factors, health status, and comorbidities. There was no significant association between short and long sleep duration and stroke in the individuals who reported good general health status. However, in individuals who reported poor health status, short sleep duration (aOR = 2.11; 95% CI 1.30-3.44) and long sleep duration (aOR = 1.86; 95% CI 1.08-3.21) were significantly associated with increased risk of stroke, compared with normal sleep duration (7-8 h per day). Disability was significantly associated with stroke in both self-reported good and poor health groups. Rural residence was significantly associated with a lower risk of stroke among individuals who reported poor health status.
conclusionsBoth short and long sleep duration were significantly associated with stroke among individuals who reported poor health. Stroke prevention should be focused on elderly individuals who believe that they have health problems.
