Short sleep, lifestyle, cardiovascular risk, and health awareness among Polish final-year secondary school students: findings from a nationwide study.
Article in Frontiers in sleep, 2026. 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
Background: Sleep is an important regulator of metabolic and cardiovascular health. Insufficient sleep is associated with adverse health behaviors and increased cardiovascular risk in young adults. Understanding sleep patterns and risk awareness in this group is essential for prevention. Methods: A nationally representative cross-sectional survey was conducted among 9,874 final-year Polish secondary school students. The questionnaire assessed sleep duration, physical activity, diet, alcohol and tobacco use, screen time, body mass index (BMI) and blood pressure. Associations between weekday sleep duration and lifestyle factors and cardiovascular risk were analyzed. Results: Over 46% of students reported sleeping less than 7 h on weekdays, with longer sleep on weekends (6.7 ± 1.3 vs. 9.0 ± 1.5 h, Conclusions: Insufficient sleep is common among Polish young adults and is associated with an unfavorable behavioral and cardiometabolic risk profile.
