Examination of parent-reported differences in children's daily screen use, sleep, and sleep hygiene behaviors during the school year and summer and their association with BMI.
Article in Sleep health, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveThe current study examined school-summer differences in children's sleep patterns and sleep hygiene. Cross-sectional relationships with children's sleep, sleep hygiene, and weight status were explored during the school year and summer.
methodsChildren (5-8 years) and their parents (n = 197 dyads) were recruited from 4 schools in southeastern Texas and via Facebook. Parents reported children's school year and summer sleep, sleep hygiene, and screen media use. Children's body mass index (BMI) was objectively assessed at the beginning and end of the summer. Associations between children's sleep hygiene and screen media use, sleep duration, and weight status were explored.
resultsChildren's sleep midpoint was earlier during the school year (1:54 AM ± 0.03) than in the summer (2:06 AM ± 0.03; t = 4.07, p < .0001). During summer, children increased their screen media use by 38 minutes (t = 2.32, p = .023) and decreased their caffeine intake from 7.43 to 7.0 (with scores ranging from 3 to 15; t = 2.83, p = .006). Greater sleep-inhibiting (β = 0.40, p = .011) and fewer sleep-promoting (β = -0.28, p = .049) behaviors during the school year were associated with having a higher BMI. There were no associations among sleep patterns, sleep hygiene and BMI during summer.
conclusionsMore positive school year sleep hygiene behaviors were supportive of having a healthier weight status. Changes in these behaviors during the summer did not portend worse weight outcomes. Supporting families in the establishment of sleep-promoting behaviors, particularly during the school year may help address the child obesity epidemic.
