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

backgroundThe purpose of this study was to develop a digital self-harm scale suitable for Chinese adolescents, and to test its reliability and validity.

methodsThrough semi-structured interview, literature analysis and expert evaluation, the initial questionnaire was developed, and 1651 students from three middle schools in Jilin Province were selected for questionnaire survey. Item analysis and exploratory factor analysis were carried out, and 843 students were selected for confirmatory factor analysis, convergent validity, discrimination validity, criterion validity, content consistency reliability and retest reliability.

resultsThe results showed that the digital self-harm scale consisted of eight items divided into two factors, namely External self image harm and Inner self emotional harm. And 73.47% of the total variance was explained. The two-factor structure model fitted well ( LIMITATIONS: The Inner self emotional harm dimension has few questions, the relationship and mechanism between digital self-harm and non-suicidal self-injury is not deep enough.

conclusionsThe digital self-harm scale developed in this study has good validity and reliability, and can be used as a measurement tool to assess the digital self-harm of Chinese adolescents.
