High prevalence of poor sleep quality and sleep deficit: A study in children, adolescents, and adult soccer players.
Observational study in PloS one, 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
objectiveThis observational study aimed to provide insight into the sleep behaviors, chronotypes, and sleep needs of athletes by examining children, adolescents, and adult soccer players from different competitive levels.
methodsThe study included 864 soccer players (n = 747 males) of various age groups [median age: 17 (interquartile range: 14-20)]. The participants completed an online questionnaire that included demographic questions, the Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS), the Morningness-Eveningness Questionnaire (MEQ), and a question about their sleep needs.
resultsAdult players had a higher prevalence of poor sleep quality, excessive daytime sleepiness, and sleep deficit than children and teenagers (p < 0.001). Lower sleep duration was associated with poorer sleep quality and excessive daytime sleepiness (rs = -0.59 to -0.17, p < 0.01). Sleep needs were significantly higher than the habitual sleep duration in teenagers (42 min, p < 0.001) and adult players (41 min, p < 0.001). Players that had poor sleep quality (OR = 3.98, 95% CI: 2.78-5.77), excessive daytime sleepiness (OR = 3.72, 95% CI: 2.32-6.1), evening chronotype (OR = 2.54, 95% CI: 1.48-4.40), and later ending time of training (OR = 1.12, 95% CI: 1.07-1.19) could be at a higher risk of having sleep deficit.
conclusionNearly half of the adult players had poor sleep quality. Additionally, one-third of the children, and almost half of the teenagers and adult players, had a sleep deficit. Players with poor sleep quality, an evening chronotype, excessive daytime sleepiness, and a later training time might be at a higher risk of experiencing a sleep deficit.
