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
backgroundThe "Inventory of Statements About Self-Injury" (ISAS) is one of the most widely used and reliable psychometric tools for assessing non-suicidal self-injury (NSSI) and its motivations. The Russian adaptation of the ISAS, involving patients with nonpsychotic psychiatric disorders, demonstrated high internal consistency and a two-factor structure similar to the original. However, the reliability and suitability of ISAS in a non-clinical population remain unclear.
aimTo adapt the ISAS in Russian, evaluate its psychometric properties, and analyze its factor structure in a sample of Russian university students.
methodsThe psychometric properties and factor structure of the adapted ISAS version were evaluated through an anonymous online survey of Russian university students. Respondents had reported lifetime NSSI and scored above 4 on the ISAS-Functions subscale. Exploratory and confirmatory factor analysis (EFA/CFA) were performed on two randomly formed subgroups to evaluate the factor structure of ISAS. Additionally, the associations between the identified ISAS factors and the presence of suicidal thoughts and attempts over a lifetime and in the week before their participation in the study, as well as seeking psychiatric and/or psychotherapeutic care over a lifetime, were analyzed.
resultsThe survey included 3,919 participants, of whom 1,149 (29.3%; 88.0% female) reported NSSI, with a median age of 20 (18; 22) years. The Russian ISAS demonstrated high internal consistency (Cronbach's alpha = 0.851). EFA results supported the original two-factor structure. CFA results suggested an alternative three-factor structure of the ISAS, including "Signal", "Regulation", and "Influence" factors. Suicidal attempts were associated with the factors "Regulation" and "Influence", suicidal thoughts with "Regulation" and female gender, and the seeking of psychiatric and/or psychotherapeutic care with "Regulation" and age.
conclusionThe adapted ISAS in Russian is a reliable tool with high internal consistency. The study proposed a three-factor structure, indicating a greater heterogeneity of the NSSI phenomenon compared to earlier understandings. The study demonstrated the association between two of the three identified factors with suicidal behavior and thoughts, and the seeking of psychiatric care.
