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

objectiveDespite common bio-behavioural mechanisms underlying maladaptive sleep and eating, little is known about their temporal associations. The present study aimed to assess the longitudinal relationship between weight loss behaviours (age 13) and sleep (age 17/18) in adolescents (N = 5705) from the '98 Growing Up in Ireland cohort.

methodUsing structural equation modelling, regression models were specified and excessive online behaviours (age 17/18) were tested as a moderator, while depressive symptoms (age 13) were tested as a mediator for the prospective association.

resultsWeight loss behaviours significantly predicted falling asleep at inappropriate times (β = 0.16, SE = 0.04, p < 0.001) and shorter sleep duration (β = 0.06, SE = 0.02, p < 0.001), but no other sleep behaviours. Associations with falling asleep at inappropriate times were partially mediated through depressive symptoms. Associations with shorter sleep duration were fully mediated by depressive symptoms. Excessive online behaviours did not moderate the relationship between sleep and weight loss behaviours.

conclusionsIn line with clinical research, this study provides preliminary evidence for the longitudinal relationship between weight loss behaviours and shorter sleep. Further research into the causal and potentially bi-directional relationship between sleep and disordered eating is needed to aid in preventing the exacerbation of both symptom presentations and to inform general health promotion strategies.
