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.

Abstract
backgroundNon-suicidal self-injury (NSSI) is a transdiagnostic symptom associated with substantial clinical burden and increased risk of suicidal behavior. Although NSSI occurs across a wide range of psychiatric disorders, research has consistently linked it to maladaptive personality traits. However, most studies have compared individuals with NSSI to healthy controls, limiting our understanding of which personality traits are specifically associated with NSSI. The inclusion of clinical control groups may therefore help clarify which personality traits are associated with NSSI rather than with psychopathology more broadly. This study aimed to investigate whether individuals with psychiatric disorders and active NSSI differ in personality traits, as assessed with the Personality Inventory for DSM-5 (PID-5), compared to those with prior but no active NSSI and those without a history of NSSI.
methods231 individuals at a psychiatric outpatient unit completed the PID-5 and the Inventory of Statements About Self-injury and were assessed with regards to demographic information, psychiatric illness and previous suicide attempts. Symptom levels of depression and anxiety were measured. Participants were divided into groups of active NSSI (≥ 5 episodes in the past 12 months; n = 123), previous NSSI (≥ 5 episodes, but none in the past 12 months; n = 68) and no previous history of NSSI (n = 40).
resultsParticipants with active NSSI scored significantly higher in negative affectivity (F(2, 224) = 10.33, p < .001, η
conclusionsActive NSSI seems to be associated with increased traits of negative affectivity and psychoticism. This study contributes with new knowledge regarding NSSI and personality traits, which may guide future research on mechanisms, etiology, and treatment approaches.
