1 · What the graph read from it

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.

2 · The registry

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

Suicidal ideation tends to be hidden, limiting the ability of current assessment tools to reliably identify at-risk individuals. Based on the spreading activation model, this study developed the Suicide Stem Completion Measurement (SSCM) as an implicit assessment tool. First, the stem was determined and evaluated by experts. Subsequently, 2,250 adolescents were recruit from two middle schools to completed the SSCM and other relevant measures. Finally, an exploratory study with a small sample compared participants based on interviews and questionnaires, both of which confirmed the presence of self-injurious thoughts and behaviors. The results showed that: (1) The single-dimensional structure of the SSCM was good; (2) The scale showed acceptable internal consistency and split-half reliability; (3) Different clusters were effectively distinguished, and good correlations with various criterion validity were demonstrated; (4) The ROC curve analysis showed that SSCM had an AUC of 0.76 for identifying suicide risk; (5) Analyses based on both interview and questionnaire data revealed that participants with self-injurious thoughts and behaviors scored significantly differently on the SSCM compared to the control group. However, no significant difference was found between the two at-risk groups. These findings indicate that the SSCM demonstrates potential utility as an effective tool for assessing suicide risk.
