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
Adverse childhood experiences and rumination are both risk factors for non-suicidal self-injury (NSSI) in depression. However, the interaction among these three factors has not been well researched. This study aimed to investigate the potential mediating role of rumination between adverse childhood experiences and NSSI frequency. To this end, 276 young patients aged 15–30 years with major depressive disorder (MDD) were recruited as the research subjects. General demographic scales and clinical scales were used to assess adverse childhood experiences, rumination, levels of anxiety and depression, as well as the frequency of NSSI. Based on DSM-5 diagnostic criteria for NSSI, MDD patients were divided into two groups: the NSSI + group (n = 134) and the NSSI- group (n = 142). Mediation analysis was employed to examine the mediating role of rumination in the relationship between adverse childhood experiences and NSSI frequency. The NSSI + group exhibited higher adverse childhood experiences, rumination scores and anxiety/depression levels than the NSSI − group (all p < 0.05). After adjusting for demographic covariates, adverse childhood experiences and different types of rumination (depression related, brooding and reflection) were positively linked to NSSI frequency over three time periods (past month/past 6 months/past year). Additionally, the depression related and brooding subtypes of rumination mediate the relationship between adverse childhood experiences and NSSI frequency. Thus, this study indicates an association between adverse childhood experiences, rumination, and NSSI. These findings suggest that heightened awareness of childhood experiences, combined with interventions targeting rumination, may help reduce the risk of NSSI.
