Psychotic-like experiences and non-suicidal self-injury in the community population: a systematic review and meta-analysis.
Review in Child and adolescent psychiatry and mental health, 2026. 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
backgroundThe aim of the study was to systematically examine the association between psychotic-like experiences (PLEs) and non-suicidal self-injury (NSSI) in community populations through meta-analysis, with a focus on prospective evidence regarding this association and potential psychosocial correlates.
methodsA comprehensive search was conducted in PubMed, PsycINFO, and Embase from inception to August 2025. Studies reporting quantitative data on the association between PLEs and NSSI in community populations were included. A random-effects meta-analysis was performed to estimate the pooled odds ratio (OR) with 95% confidence interval (CI). This association was further examined through a preliminary prospective meta-analysis of two longitudinal studies reporting adjusted odds ratios for the prediction of incident NSSI by baseline PLEs. Potential sources of heterogeneity were explored by exploratory subgroup analyses across study design, geographical region, gender composition, NSSI assessment methods, and assessment time window match between PLEs and NSSI.
resultsEight studies involving 19,719 participants were included in the meta-analysis, and an additional eleven studies were included in the narrative synthesis. Individuals with PLEs had a significantly increased odds of NSSI compared to those without PLEs (OR = 3.09, 95% CI [2.05-4.66], p < 0.001). A prospective analysis of two longitudinal studies indicated that baseline PLEs significantly predicted incident NSSI at follow-up (OR = 2.17, 95% CI [1.56-3.02]). The estimated prevalence of PLEs and NSSI in community populations was 11.0% (95% CI [7.9%-15.2%]) and 6.9% (95% CI [4.3%-11.1%]), respectively. Narrative synthesis suggested that depressive symptoms, childhood adversity, bullying victimization, and pandemic-related stress were associated with higher odds of NSSI, whereas social support was associated with lower odds.
conclusionsThe findings demonstrate a robust association between PLEs and NSSI in community populations. Preliminary prospective evidence from a limited number of longitudinal studies further suggests that baseline PLEs may predict incident NSSI at follow-up, although this finding warrants confirmation in future research.
