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
introductionYouth media guidelines in Canada and the United States recommend that bedrooms should remain screen-free zones. This study aims to verify whether bedroom screens at age 12 years prospectively predict academic and social impairment by age 17 years.
methodsParticipants were from the Quebec Longitudinal Study of Child Development birth cohort (661 girls and 686 boys). Linear regression analyses estimated associations between having a bedroom screen (television or computer) at age 12 years and selfreported overall grades, dropout risk, prosocial behaviour and likelihood of having experienced a dating relationship in the past 12 months at age 17 years, while adjusting for potential individual and family confounding factors.
resultsFor both girls and boys, bedroom screens at age 12 years predicted lower overall grades (B = -2.41, p ≤ 0.001 for boys; -1.61, p ≤ 0.05 for girls), higher dropout risk (B = 0.16, p ≤ 0.001 for boys; 0.17, p ≤ 0.001 for girls) and lower likelihood of having experienced a dating relationship (B = -0.13, p ≤ 0.001 for boys; -0.18, p ≤ 0.001 for girls) at age 17. Bedroom screens also predicted lower levels of prosocial behaviour (B = -0.52, p ≤ 0.001) at age 17 years for boys.
conclusionThe bedroom as an early adolescent screen-based zone does not predict long-term positive health and well-being. Pediatric recommendations to parents and youth should be more resolute about bedrooms being screen-free zones and about unlimited access in private exposures in childhood.
