1 · What the graph read from it

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.

2 · The registry

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

STUDY

objectivesTo determine whether within-person changes in total physical activity (PA), moderate-to-vigorous physical activity (MVPA), and sedentary time from ages 6 to 18 predict changes in sleep duration and insomnia symptoms, and vice versa.

methodsSeven waves of biennially collected data from a birth cohort study were used, capturing ages 6-18 years (n = 880). Every second year, objective data on PA, sedentary time, and sleep duration were collected using accelerometers, while insomnia symptoms were assessed through clinical interviews. Random Intercept Cross-Lagged Panel Models were estimated to test the within-person relations between PA/MVPA/sedentary time and sleep. Potential sex and age differences were also examined.

resultsWe found no evidence for within-person relations between the study variables, nor for any sex or age differences.

conclusionsChildren and adolescents who become more physically active or spend less time in sedentary activities are probably not more likely to sleep longer or better than they typically would. Statement of Significance Increased physical activity (PA) or reduced sedentary time is assumed to improve sleep, and improved sleep is expected to promote PA. While some short-term studies on daily variations in these behaviors partially support this assumption, longer-term studies are few and have substantial methodological limitations. This study is the first to test within-person relations between PA/sedentary time and sleep in children and adolescents, analyzing seven waves of data assessed by objective measures and clinical interviews. No evidence for long-term relations between PA and sleep at the individual level was revealed, thus the findings suggest that individual-level interventions targeting one behavior may not improve the other over the long term.
