Unrecognized Sleep Difficulties and Caregiver Awareness at School Entry: A Population-Based Study of First-Grade Children.
Article in The Journal of school health, 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
backgroundSleep difficulties are common in childhood and affect behavior, emotional regulation, and school functioning, yet are often unrecognized by caregivers.
methodsThis population-based, repeated cross-sectional study included 1168 first-grade children (6-7 years) in Évora, Portugal. Sleep was assessed using the Portuguese Children's Sleep Habits Questionnaire (CSHQ-PT) and a structured family questionnaire. Associations with sociodemographic and family factors were examined using multivariable logistic regression; short sleep duration was analyzed using penalized logistic regression.
resultsAcross cohorts, 46%-49% of children met the criterion for clinically significant sleep disturbance (SDI ≥ 48). Bedtime resistance, daytime sleepiness, and sleep-related anxiety were the most prevalent difficulties. Fewer than 10% of caregivers reported sleep problems, even among affected children. Clinically significant sleep disturbance was associated with caregiver education and later dinner timing, while longer commuting distance was associated with short sleep duration. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY: Findings support brief sleep screening and family-oriented sleep health guidance at school entry.
conclusionMany children begin primary school with unrecognized sleep difficulties, highlighting the value of integrating sleep health into early school health frameworks.
