Effects of sleep on multimodal cognitive functioning in college students.
Article in Frontiers in psychiatry, 2025. 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
Objective: While sleep disturbances are known to be associated with cognitive decline, the impact of sleep duration and sleep disturbances on cognitive functions remains poorly characterized in college students. This study aimed to quantify the prevalence of insomnia and poor sleep quality in a large sample of college students, and to elucidate the link between sleep disturbances and declines in different cognitive functions. Methods: The sample consisted of 1021 college students who completed a web-based survey containing the Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), and Multimodal Cognitive Ability Self-Assessment Scale (MASQ). Data were analyzed using one-way analysis of variance (ANOVA) and generalized linear models (GLM). Results: A total of 54.1% of college students reported insomnia, and 58.9% of the sample had poor sleep quality. Regarding sleep subgroups, shorter sleep duration was significantly associated with more severe sleep disturbances, including poor sleep quality (p<0.001), insomnia (p<0.001), difficulty falling asleep (p=0.001), daytime dysfunction (p<0.001), and Delayed Sleep-Wake Phase Disorder (DSWPD) (p<0.001). These sleep disturbances were associated with poorer cognitive performance. Furthermore, sleep disturbances, including difficulty falling asleep, difficulty staying asleep, waking up too early, daytime dysfunction, and DSWPD, were negatively associated with different cognitive functions: language, visual-perceptual ability, verbal memory, visual-spatial memory, and attention/concentration. Conclusion: The results of this study suggest that insomnia and poor sleep quality are common in college students, and short sleep duration exacerbates sleep disturbances, a combination that can lead to declines in cognitive functions.
