The relationship between structural campus climate and non-suicidal self-injury among middle school students: the chain-mediated roles of physical exercise and school bullying.

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.
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
Background: A structural campus climate (SCC) represents the organizational and orderly dimension of school climate. A high level of SCC means that a school possesses fair rules, reasonable value systems, and safety guarantees, all of which are key factors influencing adolescents' problem behaviors. Method: This study aimed to examine the relationship between SCC and non-suicidal self-injury (NSSI) among middle school students, and to analyze the chain-mediated roles of physical exercise (PE) and school bullying (SB). A total of 637 middle school students were surveyed using the Delaware School Climate Scale, Physical Activity Level Scale, School Bullying Scale, and Non-suicidal Self-injury Assessment Questionnaire. Results: SCC was and positively associated with PE, and SB was positively associated with NSSI. SCC and PE were each negatively related to SB; SCC and PE were also negatively related to NSSI. After controlling for factors such as gender, age, grade and only-child status, the mediation analysis indicated that the total effect of SCC on NSSI among middle school students was significant (β = -0.454, Conclusions: PE and SB not only play independent mediating roles in the relationship between SCC and NSSI, but also function as sequential mediators in a chain-mediated pathway. The research findings underscore the importance of continuously optimizing the SCC in the intervention process for NSSI behavior among middle school students. On this basis, enhancing PE and reducing SB may provide effective avenues for alleviating NSSI behavior in this population.
