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

introductionThis study aimed to examine the associations between adolescent characteristics and sleep habits in Hong Kong.

methodsA cross-sectional study was conducted among secondary school students in Hong Kong. Data on sociodemographics, health behaviors, mental toughness, and sleep patterns were collected. Univariable and multivariable logistic regression analyses were used to identify factors associated with late bedtime, insufficient sleep duration, and late wake-up time.

resultsAmong 1345 adolescents surveyed, 60.1% reported late bedtime, 56.6% experienced insufficient sleep duration (<8 h), and 34.1% reported late wake-up time. In multivariable models, older age was consistently associated with adverse sleep habits (aOR

conclusionThis study identified high rates of adverse sleep habits among Hong Kong adolescents and demonstrated strong associations with age, screen use, dietary behavior, and other lifestyle factors. These findings highlight the need for targeted interventions-such as digital use guidelines and school-based breakfast programs-to promote healthy sleep patterns during adolescence.
