Inside the world of non-suicidal self-injury e-communities: Language, identity and need for belonging.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Non-suicidal self-injury e-Communities are increasingly gaining popularity, and people who self-harm are turning to these groups to share their experiences and feelings. They are doing so through a unique set of specific slang words related to the behaviour of self-harm that seems to be pertinent to these e-communities. In this regard, this study aims to explore slang words and differences in their usage across communities. A sample of 410 posts and respective comments were extracted from two self-harm e-communities on Reddit based on predetermined slang keywords through Python Reddit API Wrapper. A content analysis was performed, indicating that slang words prevailed across 8 different domains; the 3 most prevalent were sense of belonging, medical care, and sarcasm and self-deprecation. Inter-rater reliability of the analysis found strong agreement across the 3 individual coders. Chi-square analyses were then performed to evaluate differences in the frequency of domains and subdomains between the two self-harm e-communities. Significant differences were observed across subdomains (X2 = 244.9, p = 0.001) but not across the domains. Finally, sentiment analysis was conducted, and Mann-Whitney U-tests across the two communities found that one of the two is significantly more negative in sentiment value (U = 23808, p = 0.019) while, consequently, the other had a significantly larger overall compound sentiment score (U = 17429, p = 0.003). Overall, lived experience findings from the textual descriptions of users indicate the pervasiveness of slang words across these communities and the further need to investigate their nuanced and varied usage. Building on the person-centred framework in NSSI research, a case is made for the development of more targeted and tailored interventions, such as e-health mobile and application-based interventions, that consider the unique contributions of NSSI e-Communities in the life and context of a person who engages in self-harm.
