Relationship of Emotional Functioning in 9-12-Year-Old Schoolchildren with Key Lifestyles: Sleep Quality and Daily Physical Activity.

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/
objectivesSleep problems and physical activity are key lifestyle behaviors associated with children's socioemotional development. However, their relative contribution to emotional regulation and emotional instability during middle childhood remains insufficiently clarified. This study aimed to examine the associations between sleep problems, habitual physical activity, and emotional regulation in elementary school children, while controlling for sociodemographic and lifestyle confounding variables.
methodsA cross-sectional study was conducted with 386 elementary school children (mean age = 11.15 ± 0.66 years; 45.6% boys) from southern Spain. Emotional regulation was assessed using the Emotion Regulation Checklist (ERC), sleep problems were measured with the Children's Sleep Habits Questionnaire (CSHQ), and habitual physical activity was evaluated using the Physical Activity Questionnaire for Children (PAQ-C). Age, sex, socioeconomic status, and daily screen time were included as covariates. Pearson correlations and multiple linear regression analyses were performed.
resultsSleep problems were strongly associated with lower adaptive emotional regulation and higher emotional lability. In adjusted regression models, sleep problems emerged as the most robust independent predictor of both emotional regulation and lability. Although habitual physical activity was significantly associated with emotional outcomes at the bivariate level, its predictive strength decreased after adjustment for covariates and did not independently predict adaptive emotional regulation.
conclusionsSleep problems appear to play a central role in children's emotional functioning during middle childhood. Interventions aimed at promoting socioemotional well-being may benefit from prioritizing sleep health alongside physical activity within a comprehensive 24 h movement behavior framework.
