A multidimensional examination of pain threshold and non-suicidal self-injury: psychological and physiological determinants in adolescents.

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 (NSSI) is a major clinical and public health issue in adolescence. Although psychological factors such as depression, anxiety and emotion dysregulation have been widely examined, less is known about how pain perception and autonomic reactivity interact with these variables in NSSI.
aimsThis study aimed to compare pressure pain threshold (PPT), autonomic responses and psychological characteristics between adolescents with NSSI and healthy controls, and to explore associations between pain perception, psychopathology, emotion regulation and NSSI functions.
methodSixty-eight adolescents (34 with NSSI, 34 controls) participated. PPT was assessed using a pressure algometer. Depressive symptoms, anxiety symptoms and emotion regulation difficulties were measured, and NSSI functions were evaluated using a standardised tool. Systolic (SBP)/diastolic blood pressure and heart rate were recorded before and after pain stimulation. Correlational analyses and mixed (repeated measures) analyses of variance were performed.
resultsThe NSSI group showed a significantly higher PPT than controls (mean difference 1.43 kg/cm
conclusionsAdolescents with NSSI demonstrate elevated pain thresholds and altered autonomic reactivity. These findings highlight the importance of considering pain processing alongside psychological characteristics and NSSI functions in clinical assessment and intervention planning.
