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
Background: Previous studies have indicated that negative emotions are one of the primary causes of non-suicidal self-injury (NSSI) behavior. This study focuses on examining the characteristics of large-scale brain network dynamics associated with pain perception in NSSI adolescents following experiences of negative emotions. Methods: A total of 44 adolescents with Major Depressive Disorder (MDD) and NSSI (MDD+NSSI group), 21 MDD adolescents without NSSI (MDD group), and 25 healthy controls (HC group) were recruited. Two emotional conditions (neutral and negative) were established, followed by the simulation of pain conditions using ice water stimulation, while electroencephalogram (EEG) signals were recorded using a 64-channel EEG system. Statistical analysis was conducted using mixed-design repeated measures analysis of variance, with multiple comparisons corrected using the Bonferroni method. Results: In the MDD+NSSI group, after sadness induction, the duration, time coverage of microstate A, and the transition rate from microstate B→A during the Cold Pressor Test (CPT) were significantly higher compared to neutral emotion induction. Conversely, the occurrence frequency of microstate B decreased markedly. Under neutral emotion induction, the MDD group exhibited higher occurrence frequency of microstate A and transition rate from microstate D→A than the HC group. In contrast, the occurrence frequency, coverage of microstate B, and transition probabilities from microstates C/D→B were significantly lower in the MDD group than in the HC group. Conclusion: Our findings suggest that adolescents with MDD who exhibit NSSI behavior display abnormalities in large-scale brain network dynamics associated with pain perception following experiences of negative emotions, indicating that EEG microstates may serve as neurobiological markers for abnormal pain perception in NSSI adolescents.
