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

backgroundPoor sleep quality is a prevalent health concern among Chinese adolescents. Although significant focus has been given to the impact of sleep problems on cognitive function, research on the association between sleep quality and working memory in typically developing adolescents remains limited. The aim of this study is to examine this association in Chinese adolescents.

methodsThe present study randomly recruited 2428 adolescents aged 12-18 years from four schools in Shanghai and Suzhou, eastern China in 2023 through two-stage cluster sampling. Information on sleep quality was collected using the questionnaire (Pittsburgh Sleep Quality Index). Adolescents' working memory was evaluated using the N-back task. A general linear regression analysis was conducted to evaluate the association between sleep quality and working memory, adjusted for potential confounders. Interaction terms, representing the product of sleep quality and each modifier, were included to test for interaction effects.

resultsIn the adjusted model, adolescents with good sleep quality served as the reference group. Those with poor sleep quality had increased reaction times by 0.11 s (95%CI:0.09-0.13) during the 1-back task and by 0.10 s (95%CI:0.08-0.12) during the 2-back task. Moderate-to-vigorous physical activity (MVPA) time, cardiorespiratory fitness (CRF) and age significantly modified the associations between sleep quality and working memory (P for interaction < 0.05).

conclusionsChinese Adolescents with poor sleep quality exhibited poorer working memory, particularly among those who were younger, had insufficient MVPA time, and lower CRF. Good sleep quality is significant in improving cognition function among Chinese adolescents.
