Impact of Insufficient or Excessive Sleep Duration on Cognitive Function After Stroke: The Norwegian Cognitive Impairment After Stroke Study.
Article in Journal of the American Heart Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe impact of sleep duration on cognition, particularly in the context of poststroke cognitive impairment, is not fully understood. Therefore, our objective was to investigate how sleep duration after stroke predicts poststroke cognitive impairment. METHODS AND
resultsPatients admitted with acute stroke between 2015 and 2017 were consecutively recruited to the Nor-COAST (Norwegian Cognitive Impairment After Stroke) study and invited to follow-up assessments at 3 and 18 months. Time in bed, used as a surrogate for sleep duration at 3 months post stroke, was measured using the activPAL thigh-worn sensor over a 3-day period. Sleep duration was categorized into 3 groups: <7 hours (insufficient), 7 to 9 hours (reference), and ≥9 hours (excessive). Cognitive impairment was assessed based on the
conclusionsInsufficient or excessive sleep duration was associated with poststroke cognitive impairment.
