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

backgroundUnhealthy weight control behaviors (UWCBs) are widespread in adolescents and have devastating consequences. Friendship network is potentially an important influence on university students' UWCBs. This study employs social network analysis to investigate the homophily of UWCBs among university students within peer networks and gender differences.

methodsA longitudinal study comprising two data collection waves was conducted on 612 undergraduate students from five schools at two universities in Guangdong Province, China, forming five sociometric networks. UWCBs, incorrect self-perception of obesity, depression, and anxiety were measured using standard scales. Descriptive statistics, assortativity tests and network autocorrelation models were utilized for data analysis.

resultsStudy recruited 214 (34.8%) males and 398 (65.2%) females, with the UWCBs prevalence of 28.6% (T0) and 30.0% (T1). A significant homophily of UWCBs enhancing with time was identified (ρ

conclusionsOur study found significant homophily and gender differences in UWCBs among first-year university students. These findings highlight the importance of considering peer networks and gender in future interventions.
