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
backgroundNon-suicidal self-injury is a significant clinical concern in adolescent psychiatry and frequently co-occurs with a range of psychiatric disorders, including mood disorders, eating disorders, substance use disorders, and personality disorders. With the inclusion of non-suicidal self-injury disorder (NSSID) as a distinct diagnosis in the DSM-5, growing attention has been directed toward its relationship with established psychopathological constructs. This study investigates the association between personality pathology and NSSID in adolescent psychiatric in-patients. In particular, we analyzed the prevalence of personality disorders and impairments of personality functioning (identity, self-direction, empathy, intimacy) according to the AMPD of the DSM-5.
methodsOur sample consisted of 439 inpatients (mean age = 15.2 years, SD = 1.37; 87 males, 352 females). We used the Structured Clinical Interview for Personality Disorders, the Levels of Personality Functioning questionnaire and the Semi-Structured Interview for Personality Functioning to assess personality pathology, and a structured clinical interview to evaluate the DSM-5 criteria for NSSID.
resultsOur results show that adolescents with an NSSID show more severe impairments in all areas of personality functioning and are significantly more likely to be diagnosed with a personality disorder (54%) than adolescents with no NSSID (27%).
conclusionThese results highlight the critical role of personality pathology in adolescents with NSSID and underscore the importance of targeted diagnostic and treatment approaches. Disorder-specific interventions for adolescent personality disorders may also be effective for those with severe NSSI.
