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

objectiveScant research exists on the gender-specific association between physical activity, insomnia symptoms and depressive symptoms among adolescents. The present study investigates the direct and indirect association of insomnia and physical activity with symptoms of depression.

designIn a community-based sample (

resultsThe results showed that self-reported insomnia was highly prevalent, and the association between insomnia and depression was strong. The association between insomnia and depression was significantly stronger for girls than for boys. The effect of physical activity was substantially weaker compared to insomnia. Insomnia mediated the relationship between physical activity and depression for both boys and girls. Despite expectation based on the existing literature, BMI showed no association with symptoms of depression or physical activity.

conclusionThe results address the importance of a gender-specific approach when investigating mental health among adolescents. Given the high prevalence, interventions aimed at reducing insomnia is important in the prevention of mental illness, especially among girls.
