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
backgroundPrevious studies have consistently identified pain as a significant risk factor for suicidal behavior. Both physical and psychological pain have been implicated in the underlying mechanisms of suicidal behavior. Guided by the interpersonal theory of suicide, this study assessed how physical pain sensitivity and psychological pain tolerance jointly shape vulnerability to suicidal ideation in college students.
methodsUsing a cross-sectional design, 1013 college students were surveyed via standardized questionnaires, yielding 846 analyzable responses. Suicidal behavior was assessed using the Suicide Behavior Screening Questionnaire (SBSQ). Physical pain sensitivity and psychological pain tolerance were evaluated using the Pain Sensitivity Questionnaire (PSQ) and the Tolerance of Mental Pain Scale (TMPS-10), respectively. The relationships among physical pain sensitivity, psychological pain tolerance, and suicidal behavior were analyzed. Additionally, the mediating role of psychological pain tolerance in the relationship between physical pain sensitivity and suicidal behavior was examined.
resultsCompared to participants without suicidal ideation, those with suicidal ideation exhibited significantly higher physical pain sensitivity (p = 0.011) and significantly lower psychological pain tolerance (p < 0.001). A linear regression analysis revealed a correlation between physical pain sensitivity and psychological pain tolerance (B = -0.095, p = 0.006). Logistic regression analysis indicated that both physical pain sensitivity (B = 0.369, odds ratio (OR) = 1.446, p = 0.038) and psychological pain tolerance (B = -0.676, OR = 0.509, p < 0.001) were associated with suicidal ideation. Mediation analysis showed that psychological pain tolerance partially mediated the relationship between physical pain sensitivity and suicidal ideation. However, logistic regression analysis revealed that physical pain sensitivity did not significantly predict suicidal attempts, while psychological pain tolerance remained a significant predictor.
conclusionsThe study demonstrated that psychological pain tolerance is associated with both suicidal ideation and suicide attempts, whereas physical pain sensitivity is only associated with suicidal ideation. Psychological pain tolerance partially mediates the effect of physical pain sensitivity on suicidal ideation. Reducing physical pain sensitivity or increasing psychological pain tolerance may be effective strategies for lowering the risk of suicidal ideation.
