Fitbit-measured sleep duration in young adolescents is associated with functional connectivity in attentional, executive control, memory, and sensory networks.
Article in Sleep, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
STUDY
objectivesAdolescents often do not sleep as much as recommended by most national guidelines, which may impact their brain development. The current study aims to evaluate the relationship between objective assessment of sleep duration measured with actigraphy and brain network connectivity on functional magnetic resonance imaging (fMRI).
methodsWe used data from the 2-year follow-up of the Adolescent Brain Cognitive Development (ABCD) study comprising 3799 adolescents, ages 10-13 years old, to assess the relationship between sleep duration, measured by 2 weeks of Fitbit-derived actigraphy, and brain network connectivity derived from resting-state fMRI, using linear regression models. Linear regression analysis was also used to investigate the interaction between participant sex and sleep duration on brain network connectivity.
resultsWe identified both positive and negative correlations between mean sleep duration and 6 within-brain network and 30 between-network pairs. These included networks involved in attention (dorsal and ventral attention networks), executive control (cingulo-opercular and default mode networks), memory (retrosplenial temporal network), and sensory function (auditory and sensorimotor networks). We also identified sex-specific effects in three network pairs (auditory-retrosplenial temporal, retrosplenial temporal-sensorimotor, and visual-visual) and sex differences in functional connectivity across 23 distinct within- and between-network connections.
conclusionsSleep duration is associated with the functional network connectivity in attentional, executive control, memory, and sensory networks during early adolescence. The identification of sex-specific effects in select network pairs underscores the importance of sex as a biological variable in studies of adolescent sleep and brain development.
