Associations of sleep duration, physical activity, and longitudinal changes with the risk of fatal stroke occurrence in middle-aged to older individuals : Physical activity, sleep duration, and risk of fatal stroke.
Article in BMC public 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
backgroundSleep and physical activity (PA) are associated with the risk of stroke, but the relationships between longitudinal changes in sleep and PA habits and between their combination index and fatal stroke are unclear.
methodsIn this prospective cohort study on the risks of stroke and sleep and physical activity (PA), 26,672 participants with 951 stroke deaths in the Guangzhou Biobank Cohort Study (GBCS) and 7218 participants with 49 stroke deaths in the National Health and Nutrition Examination Survey (NHANES) were enrolled after mean follow-up times of 15.4 (SD = 3.57) and 6.71 (SD = 3.43) years, respectively.
resultsCompared with stable participants, GBCS participants with sleep durations ≤ 5 and ≥ 9 h were at greater risk for fatal all-stroke (aHR = 1.35, 95% CI: 1.10-1.66, P = 0.004; aHR = 1.47, 95% CI: 1.16-1.87, P = 0.001) and fatal ischemic stroke (aHR = 1.52, 95% CI: 1.14-2.03, P = 0.004; aHR = 1.63, 95% CI: 1.18-2.27, P = 0.003); longitudinally increased sleep duration was associated with greater risks for fatal all-stroke (aHR = 1.34, 95% CI: 1.04-1.72, P = 0.02) and fatal ischemic stroke (aHR = 1.51, 95% CI: 1.08-2.12, P = 0.02), and greater risks for fatal ischemic stroke were presented in moderate-inactive PA (aHR = 3.24, 95% CI: 1.49-7.05, P = 0.003). The NHANES substandard PA had a greater risk for fatal all-stroke (aHR = 2.86, 95% CI: 1.54-5.30, P < 0.001) than did standard PA; a greater risk of fatal all-stroke was associated with short sleep + substandard PA (aHR = 7.11, 95% CI: 2.46-20.54, P < 0.001) and normal sleep + substandard PA (aHR = 2.46, 95% CI: 1.16-5.24, P = 0.02) than with normal sleep + standard PA.
conclusionsAbnormal sleep and longitudinal changes in sleep and substandard PA are associated with an increased risk of fatal stroke occurrence; these findings may be potential indicators of future fatal stroke occurrence in relatively healthy middle-aged to older individuals.
