Napping, sleep and affect in late- and short- sleeping adolescents: An actigraphy and daily diary study.
Article in Sleep health, 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
objectivesAdolescents in the United States do not typically attain enough sleep at night due to a combination of factors, including biological maturation and academic and social commitments. This lack of sleep leads to poor cognitive, mental, and physical health outcomes. Naps may compensate for inadequate sleep, however, little is known about how napping affects nocturnal sleep and mood over time among adolescents who are poor sleepers.
methodsThe present study used daily diary and actigraphy data collected over 15days in a sample of late- and short-sleeping adolescents (n=99; M
resultsThe majority of participants (76%) napped at least once during the study period, and almost one-fifth of the sample demonstrated "habitual" or frequent napping. Nap occurrence was associated with a decrease in total sleep time by 27 minutes as well as later sleep onset time that night. Later nap offset time was associated with later nocturnal sleep onset time, and longer nap duration was associated with later nocturnal sleep onset time and lower sleep efficiency. Napping was unrelated to affect. Sex did not moderate any relations between napping and nocturnal sleep or affect.
conclusionsThe findings indicate that napping is common and generally associated with worse nocturnal sleep outcomes among a sample of late- and short-sleeping adolescents.
