Critically Ill Children Show Disrupted Sleep Patterns and Atypical Electroencephalograms: An Observational Cohort Study.
Observational study in Acta paediatrica (Oslo, Norway : 1992), 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
aimSleep disruptions are common in hospitalised children. This study described sleep in critically ill and non-critically ill hospitalised children, including young infants and patients with central nervous system injuries.
methodsThis observational cohort study included two groups: critically ill children admitted to a paediatric intensive care unit with expected stay of ≥ 48 h, and non-critically ill children with suspected sleep disordered breathing. Critically ill children were recruited within two clinical studies conducted between 2020 and 2022. Non-critically ill children were recruited from a retrospective database spanning between 2017 and 2021. Sleep was measured using polysomnography and compared with age-specific reference ranges.
resultsWe included 25 critically ill and 120 non-critically ill children. Median ages were 3.6 (1.0-20.4) and 36.7 (6.1-107.7) months, respectively. In critically ill children, nighttime total sleep time accounted for only 50.9% (49.5-55.5) of 24 h sleep. Rapid eye movement (REM) and deep sleep were reduced in 96.0% and 66.7%, respectively. Electroencephalographic (EEG) abnormalities were common (76.0%). Non-critically ill children had reduced REM sleep in early infancy and shorter, fragmented sleep in older children.
conclusionCritically ill children had disrupted sleep and atypical EEG, while non-critically ill children mainly had reduced fragmented sleep.
